Currently the whole code resides within the opencl/ tree, but the
mechanism is meant to be reused in L0 for kernel-ISA allocations
optimization (further work).
This commit is a preparation step, which extracts the generic mechanism
and moves the extracted part under the shared/ tree.

- Do not wait for GPU completion on pool exhaust if allocs are in use,
allocate new pool instead
- Free small buffer address range if allocs are not in use and
buffer pool is exhausted

Increase chunk alignment from 256 to 512.
Restores performance in some workloads with pool enabled but lowers maximum
possible number of buffers in pool from 256 to 128.
MemObj size will keep the value passed to clCreateBuffer ie. will not be
aligned up by chunk alignment.
CL_MEM_SIZE will now return same value as with pool disabled.

Use correct offset for subBuffer created with clCreateSubBuffer
Make calls to clGetMemObjectInfo for CL_MEM_OFFSET and
CL_MEM_ASSOCIATED_MEMOBJECT return values like with pool buffer disabled

If a handle cannot be obtained, like PRIME_HANDLE_TO_FD, then
properly check for the error and propagate it upwards.

Improves performance in workloads that create small opencl buffers.
To enable, set env var ExperimentalSmallBufferPoolAllocator=1
Known issues (will be addressed in further commits):
- cannot create subBuffer from such buffer
- pool buffer allocation should be reused

Use enum class for MemoryPool in GraphicsAllocation
This change will ensure that GA is constructed in the proper way
- Rename namespace for isSystemMemoryPool method
- Add method getMemoryPoolString for logging actual pool which is in used
- Remove wrong pattern in GraphicsAllocation constructor
