Sync between compute and SDMA engines can be very expensive under Windows.
Use CP DMA for tiny transfers (< 1KiB) to avoid syncs and improve performance.

[ROCm/clr commit: 473621c008]
HIP can't rely on the resource tracking, used in OCL and requires different explicit sync.
Make sure ROCCLR syncs compute only when SDMA is used and vise versa.
The new logic will allow to enable CPDMA without unnecessary waits.

Blender creates and destroys big allocations during the benchmark.
That causes big delays, because vidmm has to page-in/page-out memory.

[ROCm/clr commit: dc4ad8c99c]
Adding virtual memory management APIs to rocclr.
The HIP layer will handle virtual allocs on devices.

Some chunk memory are not guaranteed to be resident during
initial allocation. Use CPDMA to force resident.

PAL may internally align up the allocation size to the page size
reported by KMD. This will cause a mismatch in size between OCL and PAL.
To avoid this, use PAL size when updating the free memory counter on
both alloc and free.

[ROCm/clr commit: be66e29e94]
On ReBar systems the invible heap is not present, so in theory we should
fail creating the suballocation chunk, however PAL doesn't report any
errors.
To make sure we never fail, allow creating the allocation in the visible
heap and system memory.

[ROCm/clr commit: 330b674821]
Replace amd::Atomic with std::atomic. Remove make_atomic uses by
converting the variable to std::atomic and making sure the memory
order is relaxed when synchronizes-with is not needed.
Delete utils/atomic.hpp.

- Add cache free on OCL context destroy
- Remove std::mem_fun() usage, since it was removed in c++17
