Fix transpilation logic to exclude constant members and add expected output files for classes with constant members

[PTKu]

This pull request improves the handling of constant members in class transpilation, ensuring that only non-constant fields are included in generated code. It updates both the transpiler logic and the test suite to verify the correct behavior, and adds new sample files to cover this scenario.

Key changes include:

Transpiler logic update:

• Updated the eligibility check in IsMemberEligibleF to exclude constant fields from transpilation, ensuring that only non-constant members are processed.

Testing improvements:

• Added a new unit test class_with_constant_members to verify that constant members are correctly excluded from the generated code.
• Introduced new sample source and expected output files for a class with both constant and non-constant members, validating that only non-constant members appear in the generated Onliners and POCO classes for both ax and tia targets. [1] [2] [3]

These changes ensure that constant members are no longer incorrectly included in the transpiled output, improving the accuracy of the code generation process.
