This update ensures that only tests requiring supported resources are executed. Specifically:

• Introduces SUPPORTED_TEST_RESOURCES (defaulting to network) and uses it to drive both test filtering and the -u option passed to regrtest.py.

• Updates UnitTests.cmake to parse unindented support.requires(...) calls in test scripts, extracting the first argument (i.e., the required resource).

• Skips any test that requires a resource not listed in SUPPORTED_TEST_RESOURCES.

• Adds support for hardcoded resource mappings (e.g., for tests like test_zipfile64 where the requires(...) call spans multiple lines).

• Emits informative messages when tests are skipped due to unmet resource requirements.

Example of output for Python 3.11:

[...]

-- Supported test resources: network
--   Ignoring 'test_curses' requiring 'curses' resource
--   Ignoring 'test_ossaudiodev' requiring 'audio' resource
--   Ignoring 'test_tix' requiring 'gui' resource
--   Ignoring 'test_tk' requiring 'gui' resource
--   Ignoring 'test_ttk_guionly' requiring 'gui' resource
--   Ignoring 'test_winsound' requiring 'audio' resource
--   Ignoring 'test_zipfile64' requiring 'extralargefile' resource
-- Discovered 407 tests (skipping 7)

[...]

Working toward addressing:

• Add support for Python 3.10, 3.11, 3.12 and 3.13 #350
