venkat1361 22881148bd Parsing Select() expression dimension args to support range of values. (#1074) 
* dim args for select token now supports range of values instead of single integer

* dim args for select token now supports range of values instead of single integer

* modified raw_ast fmt::format

* CHANGELOG.md

* varible rename for select dim from set to map in suffix

* use : for giving range of values

* Update source/lib/rocprofiler-sdk/counters/parser/scanner.cpp

Co-authored-by: github-actions[bot] <41898282+github-actions[bot]@users.noreply.github.com>

* format

* Update CHANGELOG.md

* using map instead of unordermap for select_dimension_map
