NI-RFSG metadata from codegenerated files with some cleanup and dev status override logic

[vnktshr21]

• This contribution adheres to CONTRIBUTING.md.
• I've updated CHANGELOG.md if applicable.
• I've added tests applicable for this pull request

What does this Pull Request accomplish?

• Updated the get_development_status codegen helper logic to allow a override of development status via config_addon(this will be used for setting development status for RFSG release, which does not align with existing version based logic)
• Adding rfsg metadata files out of internal codegeneration tool
  • Corrected couple of enum names
  • Documentation corrections
  • functions.py and attributes.py will contain re-arranged entries, but the generated API being unchanged should validate that its just re-arranged
  • Few default value fields got removed
  • Repcap related fields for functions got added by the codegen tool
• Cleaned up get_deembedding_sparameters method to correctly have only one return value (matches .NET API)
  • Needed to add fancy function to get this working correctly
• Corrected session locking for write_arb_waveform methods

What testing has been done?

• System tests pass with simulated and real hardware
• API codegen shows only expected updates as diff
• Verified the development_status override logic to be working fine, if we provide a override value

It's not hurting anything, but the final return statement in write_arb_waveform is unreachable.

I didn't look too closely at the function metadata changes or the documentation changes, but I reviewed the rest and it looks okay to me.
