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_*()).

Sorry for the poor description of the changes, maybe the following is better:
In the revised patch we added a call to test_msg() suggested by Phillip to
print the character code. This helps us pinpoint exactly the byte value that
is an issue as suggested by Junio. We keep using check_int() as it allows us
to still see the actual and expected return which might help us in case func()
returned a different non-zero value when we were expecting "1". It is useful
to have the return value printed on error in case we start returning "53"
instead of "1" for "true".
