- check releaseHelper support when selecting bindless mode, if not
disabled, prefer bindless mode in L0 API
- bindless mode can be forced with DebugVariable: UseBindlessMode

Due to this flag was not properly handled on Windows, command buffer
allocations were never reused in immediate command lists in case of
host secondary buffers. This lead to huge host memory consumption
and performance degradation

This change adds space reservation in command list for returning batch buffer
start hw command.
Primary batch buffer can be run from direct submission or from KMD call and
must be aligned to required size.
Ending patch for batch buffer start must be in the last command buffer of the
command list.

This feature is part of performance improvement to dispatch and start
command buffers as primary batch buffers.
When exhausted command buffer is closed, then reserve exact space for chained
batch buffer start and bind it to the next command buffer.
When closing command buffer, then save ending pointer and
reserve aligned space.

- share same code between csr and cmd container to get default heap size
- share handling of debug flag to change heap size
- share platform level surface heap size between csr and command list
- refactor heap size files
- put heap size constant and function into namespace
- command list surface heap size increased to 2MB for xehp+ to match csr
- command list increased surface heap size only for sba tracking
- sba tracking heap consumption increased due to different reset policy

- this change uses unified approach to reuse command buffer

- state base address tracking allows to reuse base address state
- surface state slots can be reused after sba reload or cache flush
- to avoid cache flush after each reset, then allow to gradualy consume heaps
- only until natural heap depletion and then dispatch reload of sba state

- This change gets level one cache policy from cached values instead
of calling virtual methods

This is small optimization to replace virtual call and retrieved struct with
cached value.

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.

When linear stream created for command container has not enough space
for command and BB_END it will program BB_END and allocate new command
buffer allocation. Pointer returned from getSpace in this case will
return storage from new command buffer allocation.
