[llvm-dlltool] Use EXPORTAS name type for renamed imports on ARM64EC. (#99346)
Renamed entries are more tricky on ARM64EC than on other targets due
to additional symbols (we need `__imp_aux_*` in addition to `__imp_*`
and both mangled and unmangled symbol thunks). While we could extend
weak aliases to add them, it seems cleaner to just always use EXPORTAS
name type on ARM64EC targets. Unlike other targets, linkers supporting
ARM64EC need to support EXPORTAS, so there is no compatibility problem
with that.
