rocDecode Buffer Tracing Support (#315)

* Added buffer tracing support for rocdecode and updated tests to work with buffer tracing

* Updated perfetto to output args individually rather than as a string list

* Updated docstrings and operation type, changed OTF2 code to remove warning due to change in operation type

* Updated tests for review comments

* Test args exist and return value

* Updated to use string entry

* Change function name

* Updated PR to reflect review comments

* Updated for PR review comments

* Change function name
