Unity master fix case 1274470

Unity master fix case 1273662

Fixes https://github.com/mono/mono/issues/20367.

Some light massaging done by @UnityAlex to cherry pick

Remove hack from mono_free_method. Bypassing cleanup here was causing corruption to persist in mscorlib's method hashtable when a rehash occurred.  Unity profiler may need changes to avoid possessing dangling pointers. Same with the mono profiler (as the comment indicates)

https://github.com/Unity-Technologies/mono/commit/f265d9a7838c97d33e8836dfc42d1f946de09041

Needed in order to fix corruption that was occuring to mscorlib's image table on domain reload due to dynamic methods from other images being stored in a hashtable that was not being cleaned up on domain reload.

Repackage stevedore artifact to remove builds in folder structure

* Remove extra string copies.

* Teach metadata-verify.c about PE32+.

It is currently hard coded to this: Intel 386 or later processors and compatible processors but we can occasionally get other machine types so this winds up flagging dlls as invalid when it should not.
