curl_ctype.h: fix spelling in a couple of locally used macros

Browse Source 
The `ISLOWHEXALHA` and `ISUPHEXALHA` macros were introduced in commit
f65f750 and seem to be only referenced locally by the `ISXDIGIT` macro.

Judging by the `ISALPHA` macro defined in the same file, it seems like
the intention was to spell them as `IS.*HEXALPHA`.

I noticed this while reading through the code and decided to open a PR,
even if it is only a tiny change, just because I was already looking at
it and it might be useful. If there is any reason not to merge this,
please do close the PR.

Closes #20810
