Rollup merge of #111262 - ChrisDenton:normalize-msvc-output, r=cjgillot

Further normalize msvc-non-utf8-ouput

Fixes #111256 by normalizing this tests down to the essential part so that it only tests for the Unicode output we expect. Also uses a file name that should never occur outside of this test.
