tests/ui/sanitizer/hwaddress.rs: Run on aarch64 and remove cgu hack

[Enselic]

To avoid linker errors like

relocation truncated to fit: R_AARCH64_ADR_PREL_PG_HI21 against `.data.rel.ro..L.hwasan'

we need to have -C target-feature=+tagged-globals, which is documented here. I learned that here.

Closes #83989
