[L0 v2] Add full support for async alloc spec

[staniewzki]

Describe the bug

After enabling AsyncAlloc e2e tests for adapter L0 v2 in #18179, the following e2e tests fail due to unimplemented features:
AsyncAlloc/device/ooo_queue_async_alloc_from_pool.cpp
AsyncAlloc/device/async_alloc_from_pool.cpp
AsyncAlloc/device/async_alloc_from_default_pool.cpp
AsyncAlloc/device/async_alloc_zero_init.cpp

********************
FAIL: SYCL :: AsyncAlloc/device/async_alloc_from_pool.cpp (1637 of 2365)
******************** TEST 'SYCL :: AsyncAlloc/device/async_alloc_from_pool.cpp' FAILED ********************
Exit Code: 2

Command Output (stdout):
