Use aarch64-asm.h in asm code consistently, this was started in
commit c608ada288ced0268bbbbc1fd4136f56c34b24d4

Ifdef `.hidden`, `.type`, and `.size` pseudo-ops for `aarch64-w64-mingw32`
target
But that commit failed to remove some existing markings from asm files,
which means some objects got double marked with gnu property notes.
libgcc/ChangeLog:
* config/aarch64/crti.S: Remove stack marking.
* config/aarch64/crtn.S: Remove stack marking, include aarch64-asm.h
* config/aarch64/lse.S: Remove stack and GNU property markings.
