Peter Smith ba476d0b83 [LLD][ELF][AArch64] Discard .ARM.attributes sections (#125838) ...

LLVM has started to emit AArch64 build attributes sections called
.ARM.attributes. LLD does not yet have support for these so they are
accumulating in the ELF output. As the first part of that support
discard all the .ARM.attributes sections. This can be built upon by the
full implementation in LLD.

The build attributes specification only defines build attributes for
relocatable objects. The intention for LLD is that files of type ET_EXEC
and ET_SHARED will not have a build attributes in the output. A
relocatable link with -r will need a merged build attributes, but until
the merge is implemented it is better to discard.
