Revert r362994 & co "[analyzer][tests] Add normalize_plist to replace diff_plist"

Reverts r362998, r362996, and r362994 because the tests do not pass on
Windows due to CRLF changes. Adding back `-w` to diff is not enough, the
new grep substitution doesn't work on Windows, and fixing it is
non-trivial.
