[Driver] Remove misused NoXarchOption from some Windows options

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 `-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
traditionally named `DriverOption` (commit
aabb0b1) and lured some contributors to add
`NoXarchOption` to options that should not have the flag.
