Mempool may reuse memory without a wait. Hence, the timestamp has
to be preserved and can't be destroyed.

Under ROCr physical allocations don't have initial VA and require extra
flag in ROCclr. Add an option to have a mempool of physical allocations.

Mempool has capability to track dependency between streams for
faster memory reuse. Enable that capability.

Windows path still uses multi threading implementation. Hence, in graphs
all nodes are executed in a queue thread and that requires to manage
mempool in the queue thread. However, the spec allows to destory memory,
allocated in a graph, outside of the graph's execution. That may cause
mempool management to go out of sync.

Runtime has to release extra memory, held by the pools,
in synchronization points for event, stream or device.

Initial implementation for hipMemPoolExportToShareableHandle,
hipMemPoolImportFromShareableHandle,
hipMemPoolExportPointer and hipMemPoolImportPointer

The change enables VM support in graphs on Windows. That allows
to avoid caching of all allocations at the cost of map/unmap
overhead during memory create/destroy.
Change-Id: I792be00fba099e5e5d3cd44a963e1dfd6976a86d
Add memory allocation support in graph. Current implementation uses
cache from mempool to hold the allocations which belong to the graph.
Also the resource tracking is disabled at this moment because mempool
operates with hip::Stream objects, but graph has execution with
amd::HostQueue objects.

Add lock protection for access to the pool list.
Remove destroyed stream from the list of the safe streams
Change-Id: I1863b89bd3f5e188c161227cc790c3adaf72cc58
HIP_MEM_POOL_SUPPORT controls memory pool support in runtime.
Currently it's disabled by default. The initial change doesn't
include: IPC, MGPU, virtual memory alloc, suballoc, defragmentation,
internal dependencies.
