It was previously failing only for pyright but added it for all type checkers just to be sure.

Update type_checker.py
On Windows it failed with UnicodeDecodeError: 'charmap' codec can't decode byte 0x9d in position 4590: character maps to <undefined>
Otherwise couldn't run conformance on Windows at all:

cursesdependency - it was introduced in bd85af0 but apparently was never used. It was preventing running conformance on Windows ascursesis not available.Provide "utf-8" encoding explicitly to
openandsubprocess.runto fix errors on Windows.Add pytype to requirements.txt on Windows too. Previously pytype was excluded from requirements but still used in conformance code leading to errors on Windows. But now pytype is available on Windows with
pip install pytype, though it's not precompiled and may be added to conformance too.To confirm it's working, below is a diff between results of 'unexpected_fails.py' based on the current repo state vs running conformance now on Windows - and there are no changes for pytype. (No idea where are those pyre errors coming through, but it's unrelated to this PR)
