pghoshamd 793755532f SWDEV-561708 Initial shared queue pool apis (#1614)
* SWDEV-561708 Initial shared queue pool apis

* Validate params; some fixes in callback function (but still needs to be checked)

* Dtor cleanup

* minor

* Enable profiling; remove callback since aql_queue takes care of it

* setPriority and setCuMask APIs updated for counted queues

* Increasing step and minor version for rocprofiler

* Tests for CountedQueueManager

* tests

* Code refactored to make pool manager part of GpuAgent only (incomplete); unique handles issue pending

* Refactored code to support CQM inside GpuAgent and unique handles; multithreaded test added

* Changed to ASSERT_SUCCESS macros for all tests

* RIng buffer overflow test added

* tests fixed; cleanup added at hsa_shutdown

* priority conversion table changes

* Compiler warnings fixed

* Rewrite 1 test; add desc and improve SetUp() code

* Improvement

* Unififed getinfo for both counted and non-counted queues

* Address PR feedback

* Addressing feedback: memleak, data type mismatch, documentation

* improve comment

* format

* Missing HSA_API macros for roctracer

* Revert "Addressing feedback: memleak, data type mismatch, documentation"

This reverts commit 5e498a55fb3640e00d06cec63dcec79293fb23de.

* Improving acquire api doc

* release api doc improved

* error codes for release api doc
