pgsql: Remove separate locale_is_c arguments

Remove separate locale_is_c arguments

Since e9931bfb751, ctype_is_c is part of pg_locale_t. Some functions
passed a pg_locale_t and a bool argument separately. This can now be
combined into one argument.

Since some callers call MatchText() with locale 0, it is a bit
confusing whether this is all correct. But it is the case that only
callers that pass a non-zero locale object to MatchText() end up
checking locale->ctype_is_c. To make that flow a bit more
understandable, add the locale argument to MATCH_LOWER() and GETCHAR()
in like_match.c, instead of implicitly taking it from the outer scope.
