Modernization and Bug Fixes in Meta Generator

Modernization:

• Replaced complex REQUIRE… macros with new require… methods on the assert context. These methods take a lambda that executes the expression and handles all exceptions.
• This change simplifies unit tests significantly and allows IDEs to interpret the code more efficiently.
• Expressions are now encapsulated in a lambda: [&, this]() { … }, capturing variables by reference and this.
• No issues were found in our existing unit tests, even though expressions are no longer directly in the test function's scope.
• Downside: Each context adds two extra stack entries, but they are easy to identify in stack traces and we think they shouldn't pose a problem.

Bug Fixes:

• Improved the regular expression for detecting test classes in scanned code files to correctly handle base classes with namespaces.
• Fixed an issue where the same regex failed to match the final keyword after a class name.

v1.1.0

Improving the Mata Data Script for the CMake Build:

• Adding the macro UNITTEST_SUBCLASS to automatically register unit test classes that are indirectly derived from the UnitTest class.
• Updated generate_unittest_metadata.py to use consistent double quotes for all strings.
• Enhanced the handling and checking of input files and added a new _paths_to_check method.
• Improved RE_TEST_CLASS and RE_TEST_METHOD regex patterns for better readability.
• Modified Macros.hpp to add UNITTEST_SUBCLASS macro definition.

Documentation Updates:

• Adding the UNITTEST_SUBCLASS macro description.
• Rewriting, reorganizing and rephrasing the documentation to make it easier to follow and understand.
