CQ: enable `ios64_prefixed_compile` by default.

It's not actually redundant with `mac_arm64_prefixed_compile`, because
they seem to run vastly different Clang versions:

- `ios64_prefixed_compile` seems to be Clang 13 and Clang 15, depending
  on builder.
- `mac_arm64_prefixed_compile` seems to be Clang 17 right now.
