- Removed MetalContext and MetalRenderPass. - Removed all code to restart renderpasses - Added support in the RHI for a new UploadContext which allows uploads to execute before the submission of contexts using them. - Most functionality is now within MetalRHIContext and removed dependancies so that multiple MetalRHIContext's can execute in parallel. - MetalDeviceContext has been removed and replaced with MetalDevice. - Removed the previous FrameAllocator and replaced with a temporary heap based allocator. - Metal no longer uses SubmitCommandsHint and now builds/submits command buffers through RHIFinalizeContext/RHISubmitCommandLists - Added initial support for MetalRHI parallel encoding, can be tested with -rhiparallel. - Removed addition temporary allocations when uploading to buffers #rb Luke.Thatcher #jira UE-212349 [CL 35450226 by carl lloyd in ue5-main branch]
