Ivan Lozano 5ca5ef6788 Fix proc_macro dependency handling.
Currently proc_macros don't pull in the correct arch dependencies when
the host arch differs from the target arch.

This fixes how proc_macro dependencies are handled by defining them as
always being host-only and including them as dependencies for
device-modules by using AddFarVariationDependencies.

Bug: 141491501
Test: Example device rust module builds with proc_macro dependency.
