[issue37760] Refactor makeunicodedata.py: dedupe parsing, use dataclass

"from typing import *"

I like to run pyflakes time to time on the Python code base. Please avoid "import *" since it prevents pyflakes (and other code analyzers) to find bugs. Example:

$ pyflakes Tools/unicode/makeunicodedata.py
Tools/unicode/makeunicodedata.py:35: 'from typing import *' used; unable to detect undefined names
Tools/unicode/makeunicodedata.py:921: 'Iterator' may be undefined, or defined from star imports: typing
Tools/unicode/makeunicodedata.py:921: 'List' may be undefined, or defined from star imports: typing
Tools/unicode/makeunicodedata.py:921: 'Iterator' may be undefined, or defined from star imports: typing
...
