[issue32285] In `unicodedata`, it should be possible to check a unistr's normal form without necessarily copying it

The purpose of the function is to be faster than str == unicodedata.normalize(form, str). So yeah, any optimization is welcome.

But I don't bother with MAYBE suboptimal case which is implemented with: str == unicodedata.normalize(form, str). It can be optimized later, if needed.

If someone cares of performance, I will require a benchmark, since I only trust numbers :-)
