Handle IgnorePrefer32OnDevice() in first_prefer32 path properties

This was causing missing dependency errors because the arch mutator
will replace first_prefer32 with first when IgnorePrefer32OnDevice()
is set.

Bug: 372091092
Test: m nothing with aosp/3315229 on a device that sets IgnorePrefer32OnDevice()
