[Driver] Remove some misused NoXarchOption

If an option has the `NoXarchOption` flag, ClangDriver will emit an error if the
option is used after `-Xarch_*` (originally for universal macOS binary, reused
by offloading purposes `-Xarch_host`/etc). The error checking only applies to a
small set of options (e.g. `-o`) and is not very useful for most options, but
`NoXarchOption` was improperly named `DriverOption` (commit
aabb0b11) and lured some contributors to add
`NoXarchOption` to options that should not have the flag.
