meshing queries updates

• change from camel case to snake case
  • I note that this is done in PR, thanks
• reduce number of functions by grouping them and adding more arguments (gRPC)
  • E.g., all get_face_zones_* and get_face_zone_idlist_* can be merged and arguemts added (use the oneOf feature)
• make interface easier to use e.g., in GetZonesOfType("velocity-inlet") and related functions the required argument values are obscure. We can add enums in the proto file.
• add the new RPCs to the existing proto file and implement them in PyFluent, but do not document them and indicate that they are unsupported by 24R1.

We are refactoring and reducing number of gRPC helper functions. (ADO PR related to T830826 )

We have improved error handling to get idea about allowed required argument values.
