Metal: MTLMemoryManager implementation includes functions which manage allocation of MTLBuffer resources.
The memory manager includes both a GPUContext-local manager which allocates per-context resources such as Circular Scratch Buffers for temporary data such as uniform updates and resource staging, and a GPUContext-global memory manager which features a pooled memory allocator for efficient re-use of resources, to reduce CPU-overhead of frequent memory allocations.
These Memory Managers act as a simple interface for use by other Metal backend modules and to coordinate the lifetime of buffers, to ensure that GPU-resident resources are correctly tracked and freed when no longer in use.
Note: This also contains dependent DIFF changes from D15027, though these will be removed once D15027 lands.
