Program barrier to task stream, before next enqueue kernel.
This will reduce the number of batch buffer starts for sequences of
enqueue, barrier, enqueue, ... .

Group allocation types related to cpu side allocations in function to
query gmm usage type. These types will have caching enabled even if
CPU caching is not preferred by GPU.
Add logic to query whether the cpu access is allowed for an allocation
(in cases when it is not preffered by GPU).

By default prefer allocating memory first by KMD, instead of malloc first.
By default prefer not caching allocations on MTL devices. This results
in allocations being handled with non-coherent pat index.
For integrated devices when caching is not preferred do not allow
direct memory access in CPU domain. For map/unmap operations create
a dedicated memory allocation for CPU access, instead of accessing it
directly, reusing the same logic as when mapping/unmapping local memory.

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
