transform sgen_get_descriptor to parallel safe version in job_major_mod_union_preclean (#21384)
fixes #21369
Related to https://github.com/xamarin/xamarin-android/issues/6546
job_major_mod_union_preclean can race with the tarjan bridge
implementation that changes the vtable pointer by settings the three
lower bits. this results in invalid loading of the vtable
(shifted by 7 bytes) which in turn give a wrong desc to the scan
functions
