getBaseAddress was incorrectly returning pLeftBound which changes after
memory allocation.
Added baseAddress field to store and return initial address value.

This PR handles the situation in which a component
has reserved a front window space for itself in the external heap,
so that the Compute Runtime cannot access this area.
In such a situation, we perform the following steps:
1. reserve 4GB chunk in heapStandard
2. split our chunk into 2 parts: heapFrontWindow, heapRegular
3. from this point on, map all linearStream allocations in reserved 4GB
chunk
Patch applies to Windows and WSL.
Patch only applies when the bindless global allocator is enabled.

- freed pointer cannot overlap with freed chunks, therefore there is no way
to merge it with freed chunks if they overlap
Signed-off-by: Mrozek, Michal <michal.mrozek@intel.com>
Instances returned by `getAllocationsVector()` in some cases cannot be
freed (in the `malloc/new` sense) until the `drain()` function invokes
`allocInUse()` on them. Plus, the `chunksToFree` container operates on
pairs `{offset, size}`, not pointers, so such pair cannot be used to
release allocations either.
Provide an optional callback, which can be implemented by the custom
pool derived from `AbstractBuffersPool`. This callback can be used, for
example, to perform actual release of an allocation related to the
currently processed chunk.
Additionally, provide the `drain()` and `tryFreeFromPoolBuffer()`
functions with pool-independent versions and keep the previous versions
as defaults (for allocators with a single pool). The new versions allow
reusing the code for cases when allocator has multiple pools.
In both cases, there was no such needs so far but it arose when working
on `IsaBuffersAllocator`. The latter is coming with future commits, but
the shared code modifications are extracted as an independent step.

- Enabled allocation of specified base address in the targeted heap.
- Enabled virtual memory reservations to grow by allocating at the start
of the heap vs the end of the heap.
