WIP.  Also, I should add fix to perl script (genUnicodePropertyData.pl) for this.

Part 1. Make GetCharProps1 as static function

nsCharProps1 can replace with ICU, so I want that GetCharProps1 isn't exported to replace with ICU.

If ICU is available, we should use ICU API instead of using nsCharProps1

Just wondering, have you compared performance at all (e.g. talos tp numbers) to see if this makes any measurable change (either better or worse) compared to our existing code? I think character property lookup is pretty hot code.

OK, looks like this isn't going to move the needle perceptibly (either way), which is fine - thanks.

Looks OK to me. (Please make the commit message a bit more complete - e.g. insert "instead of GetCharProps1 and its supporting data", or something like that.)
