Set the encoding parameter for all open() calls that write in text mode

This was generated with a regex search/replace in vscode using:
`(open\(.*, 'w\+?')` -> `$1, encoding='utf-8')`

This should silence a bunch of warnings, and seems to fix issues seen in
the Windows CI. This seems to likely be to a "helpful feature" in
msbuild that treats certain text in stdout/stderr as errors, which it
sometimes decides that the warning about not having the encoding set
triggers.
