Apply PR feedback: simplify InvariantGlobalization gating, rename minimal_main.js

- Drop ConditionalTheory(IsMonoRuntime) on InvariantGlobalization tests; TestCategory=native already excludes them from the CoreCLR lane.
- Flip RelinkingWithoutAOT back to TestCategory=native so it runs on Mono only.
- Rename icu_main.js to minimal_main.js (the file is not ICU-specific).
