* Split IsRayTracingEnabled() into 2 parts: IsRayTracingEnabled() which can be changed at runtime and IsRayTracingAllowed() for checking if ray tracing can be enabled.
* r.Raytracing can now have following values: 0 - disabled, 1 - enabled all the time, 2 - enabled dynamic
* When ray tracing is dynamic, RayTracingGeometryManager will collect all FRayTracingGeometry and allocate/release RHI objects as needed depending on if ray tracing is enabled or not.
* Ray tracing can be switched on/off with r.Raytracing.Enable (default is 1).
* Add support to most features used in CitySample/Lyra for switching ray tracing at runtime.
* TODO: Hair geometries are not yet released.

- PCD3D_SM5 and PCD3D_SM6 had a unique situation of having identical (bytecode-wise and output hash-wise) shaders (raytracing is allowed in PCD3D_SM5). This resulted in those IoStore chunks being deduplicated, however, the actual contents were not identical due to optional data (which isn't included in the shader hash, see UE-166389).
- This fix makes sure we don't use just the shader hash alone to produce IoStore chunk hashes. Hash will now include the shader size and the shader format name.
- A few early guards added here and there to detect the problem early.
Also fixed a memory leak in UnrealPak pointed by CM.

- reduce the amount PSOs precached which won't be used during rendering
- fixes a few missing PSOs
- add some profile tags
- Minor fixes when running with PSO precaching turned on in the editor (won't do a lot right now but also won't fail or assert)

- Saves disk size and runtime memory on all platforms that use IoStore-based shader archive (on some - significantly).
- Decompression time is small and seems to get lost in noise given how rarely shaders are actually created.
- Also changed IoStore-based archive to allocate preload entries on demand, and disabled preloading singular shaders (used by the PSO cache) as the API needs more work.

- Provides about 8% runtime memory savings (in local tests).
- Also, adds more compression types for shaders.
- Impact on the shader compilation (in SCWs) seems to be negligible in local tests.
