5abb1ea6 - [test] Remove some REQUIRES: for features not longer used in those files

[test] Remove some REQUIRES: for features not longer used in those files While doing #76740 I iteratively was adding new `REQUIRES:` as new usages of the features were found, but I did not realize that at the same time other people might be removing some of those usages. The tests in this commit had some `REQUIRES:` line for a previous `-enable-experimental/upcoming-feature`, but they not longer use those features, so the `REQUIRES:` were effectively disabling the tests (at least in the case of `KeyPathWithStaticMembers`. In other cases they might still had executed).
