PVC platform with no support for atomic operations on system memory
must always allocate buffers in local memory to avoid atomic access violation.

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

This change is intended to be used in immediate command lists that are
using flush task functionality.
With this change all immediate command list using the same csr will consume
shared allocations for dsh and ssh heaps. This will decrease number of SBA
commands dispatched when multiple command lists coexists and dispatch kernels.
With this change new SBA command should be dispatched only when current heap
allocation is exhausted.
Functionality is currently disabled and available under debug key.
Functionality will be enabled by default for all immediate command lists
with flush task functionality enabled.

Improve performance by binding the command buffer together with other
allocations if VM_BIND feature is available. Remove the legacy
flag PassBoundBOToExec from DebugManager to simplify the logic.
Adapt unit tests and reuse handy macros to generate proxy mock-methods.

This change gives fine grain control over front end configuration for each
kernel.
As it gives possible to inject FE command in command queue and return to exact
place in command list.
Programming commands in queue makes patching commands in command lists
not needed as that operation is costly.
And it allows to program context information for each command list too.
