fix: Error when FreeParameters are named QASM types

[Tarun-Kumar07]

Issue: Fixes #603

Description of changes:

• The choice of name in FreeParameter is restricted now. Any SDK predefined variables or OpenQasm reserved identifiers cannot be used to as names of FreeParameter.
• OpenQasm reserved identifiers are picked from the grammar documentation of OpenQasm and OpenPulse. Only words from below sections are picked as it is more likely that user might use such names.
  • Language keywords
  • Types
  • Builtin identifiers and operations

Testing done: Unit test has been added.

I have raised another PR #268 in amazon-braket-pennylane-plugin-python to address the CI failure. I am not sure how to link both the PRs and make the CI pass here.

Can someone help?

Thanks!

Hi, I'm not sure why the Dependent tests are failing for Windows with the following error message:

I think this must have been some intermittent error downloading from PyPI. I'm re-running the failed tests and they appear to be succeeding now.
