Mark Satterthwaite a511ded42a Initial ShaderCore-level cache to start addressing shader hitches [UE-7536]. At present it is only configured by Mac OpenGL, though other APIs could use it. As all shaders & programs are cached it is inappropriate for memory constrained devices so it is only enabled by Desktop platforms.

- The consolve variable "r.UseShaderCaching" controls whether the cache should be used.
   - The cache has to be initialised and shutdown by the RHI.
   - All RHI shader types now contain the SHA hash of the compiled source when the cache is in use so that they can be identified efficiently.
   - All shaders are fetched from the cache rather than being created on-demand.
   - On shader deserialisation the new shader is sent to the render thread for creation & caching.
   - After each shader is cached all complete bound-shader-states that include that shader are constructed and cached.
   - Wrapped OpenGL glCreateShader & glCreateProgram to use name-caching as these operations can synchronise the entire OpenGL pipeline on OS X.

Developer

Core - Replaced FPlatformProcess::CreateSyncEvent with FPlatformProcess::GetSynchEventFromPool, CreateSyncEvent is not longer publicly available

- Changed FConfigCacheIni files to have a "type" that determines if Flush is called on them when they go out of scope (temporary objects were writing bad files to disk) [UE-8542]
