unit-tests: rewrite t/helper/test-ctype.c as a unit test
In the recent codebase update (8bf6fbd00d (Merge branch
'js/doc-unit-tests', 2023-12-09)), a new unit testing framework was
merged, providing a standardized approach for testing C code. Prior to
this update, some unit tests relied on the test helper mechanism,
lacking a dedicated unit testing framework. It's more natural to perform
these unit tests using the new unit test framework.
This commit migrates the unit tests for C character classification
functions (isdigit(), isspace(), etc) from the legacy approach
using the test-tool command `test-tool ctype` in t/helper/test-ctype.c
to the new unit testing framework (t/unit-tests/test-lib.h).
The migration involves refactoring the tests to utilize the testing
macros provided by the framework (TEST() and check_*()).
