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.

- bitset is 64 bit in size, context ids may go beyond that limit
when multiple devices are available
- this change subtracts contextId of first context for a given root
device - tracked state dirty contexts ids are now zero-based

Make bindless heaps resident right after heap allocation.
Motivation is that SYCL bindless image can be passed as a value argument
or through memory. Therefore, we're not able to make its bindless heap
resident during kernel initialization or setting kernel arguments.
This fixes SYCL bindless image read_write_*D.cpp tests on DG2.

- SPECIAL_SSH is used for debug surface SurfaceState which must be
located at bindless offset zero
- limit size of external front window

- introduce 2 reuse pools to bindlessHeapHelper
- one pool stores slots for reuse, second pool stores released slots
- stateCacheDirty flags keep track of state cache - when pools are
switched - flags are set indicating flushing caches is needed after
old slots have been reused for new allocations

- program surface states for redescribed images correctly. Image copy
to/from memory are using redescribed surface states,
- refactor state base address programming - program address and size
together, set max size at the beginning due to lack of Enable flag
- set GpuBase in WddmAllocation when external heap is used
- return max ssh required size from kernelInfo or based on stateful args

- store surface state info for bindless addressing in graphics
allocation
- remove map in BindlessHeapsHelper - bindlessInfo is constant for
the lifetime of an allocation
- program bindless offsets and surface states for images when used in
bindless kernel
- handle ouf of memory on surface state heap - return error
