fix: use a portable python script instead of sed in test

Differential Revision: https://phab.mercurial-scm.org/D2988

37559:c4a0626f6b6e

Set up the config with two simple fixers: one that fixes specific line ranges,
and one that always fixes the whole file. They both "fix" files by converting
letters to uppercase. They use different file extensions, so each test case can
choose which behavior to use by naming files.

approximates the behavior of code formatters well enough for our tests.
