fix regex on arm
TRE has a broken assumption that wchar_t is signed, which is a sane expectation, but not required by the standard, and false on ARM's ABI. i leave tre_char_t as wchar_t for now, since a pointer to it is directly passed to functions that need pointer to wchar_t. it does not seem to break anything. and since the maximum unicode scalar value is 0x10ffff, just use that explicitly rather than using the max value of any particular C type.
