UE5 migration:

• https://forums.unrealengine.com/t/4-25-transition-guide/142969/2
  • FShader serialize: replaced with LAYOUT_FIELD
  • FShader helpers: need to be called on a TShaderMapRef
    • TShaderMapRef<MY-CUSTOM-FSHADER> ComputeShader(GetGlobalShaderMap(ERHIFeatureLevel::SM5))
  • END_UNIFORM_BUFFER_STRUCT: no longer takes parameters
  • UNIFORM_MEMBER: replaced with SHADER_PARAMETER
• https://dawnarc.com/2020/06/ue4rhi-rendering-hardware-interface-notes/
  • ENQUEUE_UNIQUE_RENDER_COMMAND_ONEPARAMETER: replaced with ENQUEUE_RENDER_COMMAND
• https://github.com/ValentinKraft/UE4_SortingComputeShader/tree/master_4.24_transition
  • FShaderResourceViewRHIParamRef: replaced with new FRHIShaderResourceView
    • That actually resulted in a bug: using FShaderResourceViewRHIRef instead for now
• Deprecated: UnbindRenderTargets API is deprecated; EndRenderPass implies UnbindRenderTargets.
