Duplicate 4.11 CL #2887365 & CL #2887583:
Allow InfiltratorDemoEditor under Metal to issue a query buffer reset without crashing - the function that switches to the new query buffer needs to reapply some of the draw-state so that future commands don't dereference nil.
#jira UE-27513
My earlier fix for UE-27513 overlooked various internal details that meant it wouldn't restore state correctly, would fail validation and could crash in a new place. This version will ensure that cached state is only reset when it is appropriate to do so and will restore it correct when doing a query buffer reset.

Change 2900846 on 2016/03/09 by Mark.Satterthwaite
Reimplement Metal object lifetime tracking as stats in the stat-group, though the old system is maintained as a debug-only tool that could (and probably should) be extended to track over/under-release bugs. Currently the texture count will be distorted by texture SRVs so will need improvement but other stats should be reliable. In order to properly report the number of buffers the TResourcePool policy class must now define a FreeResource function, so I've added them to the appropriate places too.

Change 2900927 on 2016/03/09 by Mark.Satterthwaite
Implemented operation threshold submission of Metal command buffers to keep the GPU busier and not just idle waiting for the CPU. Whenever rhi.Metal.CommandBufferCommitThreshold is set to a value >0 and the current command buffer has >= draw/dispatch operations outstanding then the command-buffer will be committed at the next encoder boundary. The default value is 100 operations which is currently arbitrary and the feature can be disabled by setting the value to <= 0 in which case only explicit submissions will occur as previously.

Change 2905206 on 2016/03/11 by Mark.Satterthwaite
Worked around UE-27818 "ElementalDemo Causes Invalid Rendering on AMD GPUs" - recent changes to allow mesh particles to write to velocity leave a texture-buffer unbound & then use a uniform value & an if-branch to guard against access but AMD's Mac GL driver notices that the buffer is referenced in the shader but not bound & promptly tries to fallback to Apple's S/W renderer regardless of what the uniform value is. That's legal behaviour for an OpenGL implementation so the C++ code has been changed to allocate and write the current transforms into the buffer for OpenGL when they wouldn't otherwise be provided. This is sufficient to avoid the problem without affecting any other API.

Depending on shutdown order, the Slate Renderer may go away, and then render data handles may not be collected correctly because they are trying to reference a pointer that's no longer valid and cause a crash on exit. The correct approach would be to have render handles actually have a pointer back to who owns them, in this case the RHI Resource Manager, which is still alive and well at this point in the pipeline. Then if the resource manager is collected, it forces all handles to get cleaned up correctly, or if the handles are collected first, they can be sure they've got a valid pointer back to the resource manager.

Emit a shader code cache for each platforms requested shader formats, this is separate to the targeted formats as not all can or need to be cached.
- The implementation extends the ShaderCache's hooks in FShaderResource's serialisation function to capture the required shaders.
- Each target platform has its own list of cached shader formats, analogous to the list of targeted RHIs. Presently only the Mac implements this.
- Code cached shaders are now compressed (for size) to reduce the overhead associated with keeping all the shader code around - this works esp. well for text-based formats like GLSL.

TTP# 337652 - EDITOR: Limit Project supported Android icons down to 1
TTP# 337650 - EDITOR: There is only 1 icon for Apple for Project Supported Platforms
DesktopPlatform now contains a static array of FPlatformInfo. This can be used to query UE4 about its available platforms, even when they're not available as a target platform.
FPlatformInfo contains the information required by the editor (such as a localized display name and icon), as well as whether a platform is a variation ("flavor") of another, and if so, whether the flavor affects the build output (eg, Win32 or Win64), or the cook output (eg, Android_XYZ). This lets the editor build up nested menus for the "Package Project" and "Cook Project" options, rather than just showing everything as a flat list.
