As a part of the LWC work, this change primarily focues on updating FGameTime and UWorld to use doubles for accumulated time. Note that time deltas will remain as floats.
Additionally:
* A few time-related BP functions were updated to use doubles where appropriate. as well as the FRenderThreadUpdateContext struct for the Slate renderer.
* Some compilation errors were also fixed due to the change.
* Minor changes of float literals to drop the 'f' suffix.

Implement new function for switching view mode and visualize buffer before taking screenshots;
Screenshot individual buffers instead of using lighting on screenshot tests;
Fix import tests using whatever render context to import was serialized into the config for the import tests;
Disable geometry cache notification on other geometry cache tests;
Increase tolerance on test_pie_streaming_level to give more time for levels to stream in and out before checking for loaded actors;

When running with ODSC in the editor Materials can have incomplete or partial shader maps. In other words some shaders _might_ be missing. If a render system requires all shaders to be present and can't use ODSC functionality to compile the necessary shaders we need a mechanism for compiling just the missing shaders.
- Added UMaterialInterface::CacheShaders() which is implemented for UMatetrial and UMaterialInstance. The call is just forwarded along to CacheResourceShadersForRendering and InitStaticPermutation respectively.
- You can call CacheResourceShadersForRendering multiple times (even with a completed shader map) and it will not recache uniform expressions. If the Resource's shader map is complete the function is a no-op.
- FObjectCacheContext can accept a UWorld and will only return primitives that are in that world.
- Added a function SubmitRemainingJobsForWorld(UWorld* World, EMaterialShaderPrecompileMode CompileMode) that will iterate all materials used by primitives in the world and compile the missing shaders.
- SubmitRemainingJobsForWorld() is used in various scenarios in the editor to ensure _all_ shaders are compiled for all materials before proceeding.
- Explicitly try to compile UI and PP materials. Since we don't know which ones are used in the given world we just have to iterate all loaded ones. This is a potential area of optimization.
- If there are already complete shader maps (if you are not running with the shader job cache), SubmitRemainingJobsForWorld is fast and results in a no-op for each material.

1) Editor viewports now display at high DPI by default for better Gen5-console feeling in editor on high DPI monitors.
2) Realtime editor viewports now display at screen percentage based on the display pixel count. Fix screen percentage independent of the pixel range could either render not enough pixel at low display resolution or be too slow at high display resolution. Given the level editor viewport can scale in size based on editor user layout preference, monitor, the screen percentage automatically scalling based on display pixel count gives a better experience of quality consistency/GPU cost for rendering frame, especially when going level editor fullscreen with F11 or not. The curve to compute rendering resolution from display resolution is in BaseEngine.ini
3) Non-realtime editor viewports still display at a screen percentage based on OS DPI scale, independent of the display pixel count because use spatial upscaler and therefore need consistent sharpness not worst than editor fonts, but keep same rendering resolution as before to not increase out of GPU memory errors. The performance of potentially rendering at high resolution than a realtime viewport is ignored given the non real-time viewports are not rendering every frame.
4) PIE viewports now override r.ScreenPercentage by default to have consistent resolution quality and performance between realtime editor viewport and gameplay viewport by default without risk of introducing out of GPU memory errors loosing possibly unsaved editor work if the game's graphic settings default to a screen percentage higher. To advertise discoverability of this change, any update to the r.ScreenPercentage cvar will lead to a message display in console/log if overriden by editor settings or dynamic resolution settings.
5) As much as a project can change the default anti-aliasing method, can also configure on a per project basis the default screen percentage behavior in project preference that the editor user can then override locally for his/her own use with his editor settings. For instance mobile only or forward renderer MSAA only video games.
6) When working very high end work-in progress rendering tech project in a econemic context where lattest GPUs are hard to get, the range of GPU performance can vary greatly between contributor of the same projects. To provide more robustness for lowerend GPU of collegues with tech not yet scaling, the project settings now offer a MaxRenderingResolution for editor viewports that can also be overriden on a per user basis.
7) Automated screenshot already takes care of forcing r.ScreenPercentage.

Introduce bElevateLogWarningsToErrors as a good name for existing functionality. Note it's assuming the name as it's known by its customer code. This change lines up the settings variable to its colloquial name around the codebase.
Deprecate bTreatLogWarningsAsTestErrors as it was misleading because it doesn't really shuffle log warnings into the test errors bucket as much as it just reclassifies the log verbosity from log warning to log error.
Remove bTreatLogErrorsAsTestErrors as it wasn't functional outside of EditorIterationTest's custom base class, and it's tempting to use incorrectly in place of bSuppressLogErrors

Now only r.AntiAliasingMethod prevails to selects the anti-aliasing method explicitly for the deferred shading renderer. Each AA technic have it's own cvars to control their quality independently
FXAA now have its own r.FXAA.Quality. The FXAA shader permutations where mis configured with r.PostProcessAAQuality=1 & 2 both mapping to the FXAA_PC_CONSOLE=1 that is now r.FXAA.Quality=0. Instead r.FXAA.Quality now offer more mid-quality settings for FXAA_PC=1 with r.FXAA.Quality=1 & 2 & 3. Backward comaptible migration is as followed:
- r.AntiAliasingMethod=1 r.PostProcessAAQuality=0 -> r.FXAA.Quality=0
- r.AntiAliasingMethod=1 r.PostProcessAAQuality=1 -> r.FXAA.Quality=0
- r.AntiAliasingMethod=1 r.PostProcessAAQuality=2 -> r.FXAA.Quality=0
- r.AntiAliasingMethod=1 r.PostProcessAAQuality=3 -> r.FXAA.Quality=3 but with some neighborhood search setting changed in FXAAShader.usf
- r.AntiAliasingMethod=1 r.PostProcessAAQuality=4 -> r.FXAA.Quality=4
- r.AntiAliasingMethod=1 r.PostProcessAAQuality=5 -> r.FXAA.Quality=5
TAA now have its own r.TemporalAA.Quality. Backward compatible migration is as followed:
- r.AntiAliasingMethod=2 r.PostProcessAAQuality=0 -> r.AntiAliasingMethod=0
- r.AntiAliasingMethod=2 r.PostProcessAAQuality=1 -> r.AntiAliasingMethod=1 r.FXAA.Quality=0
- r.AntiAliasingMethod=2 r.PostProcessAAQuality=2 -> r.AntiAliasingMethod=1 r.FXAA.Quality=0
- r.AntiAliasingMethod=2 r.PostProcessAAQuality=3 r.TemporalAAUpsampleFiltered=0 -> r.TemporalAA.Quality=0
- r.AntiAliasingMethod=2 r.PostProcessAAQuality=3 r.TemporalAAUpsampleFiltered=1 -> r.TemporalAA.Quality=1
- r.AntiAliasingMethod=2 r.PostProcessAAQuality=4 -> r.TemporalAA.Quality=2
MSAA r.AntiAliasingMethod=3 & TSR r.AntiAliasingMethod=4 remains unchanged.
sg.AntiAliasingQuality now maps to different r.TemporalAA.Quality or r.FXAA.Quality
