runtime: use NOFRAME on arm64

This replaces frame size -8 with the NOFRAME flag in arm64 assembly.

This was automated with:

sed -i -e 's/\(^TEXT.*[A-Z]\),\( *\)\$-8/\1|NOFRAME,\2$0/' $(find -name '*_arm64.s')

Plus a manual fix to mkduff.go.

The go binary is identical before and after this change.
