  [AArch64] Emit .arch and .arch_extension during assembly to textual asm (#138433)

This patch ensures that when assembling to text (`-filetype asm`),
`.arch` and `.arch_extension` directives are preserved in the output.
This prevents errors related to unavailable extensions in the assembly
output (see #117221 for an example).

Fixes #117221.
