Florian Mayer e65e1939a1 Reland^2 "[MTE] remap stacks with PROT_MTE when requested by dlopened library" 
Also enable stack MTE if main binary links in a library that needs it.

Otherwise the following is possible:

1. a binary doesn't require stack MTE, but links in libraries that use
   stg on the stack
2. that binary later dlopens a library that requires stack MTE, and our
   logic in dlopen remaps the stacks with MTE
3. the libraries from step 1 now have tagged pointers with missing tags
   in memory, so things go wrong

This reverts commit f53e91cc81.

Reason for revert: Fixed problem detected in b/324568991

Test: atest memtag_stack_dlopen_test with MTE enabled
Test: check crash is gone on fullmte build
