It's valid for 3D image to copy 2D region.
Current checks for mip map do not consider that.
This change correctly checks for mip mapped 3D image.

If user passes slice pitch which is larger than region
to copy, do not override memory beyond region but within
that slice pitch.

The patch applies to Level Zero.
Only allocations < 2MB will be fetched from the pool.
Allocations are shared and reused within a given device.
Additionally, I added a new debug flag to control the allocator:
EnableTimestampPoolAllocator

If flag "LogUsmReuse" is set, usm reuse will log operations to csv file.
Each line will contain: timestamp, host/device, operation type,
allocation size, true/false whether operation succeeded.
This data can then be used to produce graphs and help in analyzing
usm reuse in a particular workload.

When is2MBLocalMemAlignmentEnabled returns true,
increase pool size for builtins from 64k to 2MB.
Additionally, set appropriate alignment for kernel ISA heap allocations.
Additionally, configure isaAllocationPageSize based on productHelper

- Updated `isAllocTbxFaultable` to exclude `gpuTimestampDeviceBuffer` from being
faultable.
- Replaced `SpinLock` with `RecursiveSpinLock` in `CpuPageFaultManager` and
`TbxPageFaultManager` to allow recursive locking.
- Added unit tests to verify the correct handling of `gpuTimestampDeviceBuffer`
in `TbxCommandStreamTests`.

User can read image with row pitch larger than region width.
In such cases, don't override memory which is out of region
but within row pitch.

Refactor buffer pool allocator to support configurable
SmallBuffersParams based on product helper capabilities.
This patch enables setting custom pool
parameters instead of using fixed static values.
For devices with 2MB local memory alignment enabled
(is2MBLocalMemAlignmentEnabled),
use larger pool configuration:
- Pool size: 16MB (up from 2MB)
- Threshold: 2MB (up from 1MB)
- Alignment: 64KB (unchanged)
- Starting offset: 64KB (unchanged)
This improves memory utilization for devices supporting larger memory
alignments
while maintaining original parameters for other devices.
Key changes:
- Moved params from static template to instance member
- Added SmallBuffersParams struct with default/large configs
- Added constructor and setter methods for params configuration
