Add `test-everything` annotations to more archs to ensure test coverage, and some small changes to make CI pass

 - Disable `vsx` tests for `ppc` and `ppc64`
 - Disable `tme` tests for `aarch64` and `aarch64_be`
 - Disable `frecipe` tests for `loongarch64`
 - Add `altivec` run for PPC32 (with `-C target-feature=+vsx` `qemu` gives a nasty error)
