[AMDGPU][True16][test] update VOP2 asm/dasm file with true16/fake16 (llvm#113101)

This is a non-functional change

update GFX11/GFX12 VOP2 asm/dasm test for true16/fake16:

1. duplicate files to be true16/fake16 by adding
"-mattr=+real-true16/-mattr=-real-true16" while true16 test file will be
updated to true16 format when the true16 instructions are supported
2. sort "*t16_err.s" and "*t16_promote.s" tests to alphabetic order.
This is for the upcoming true16 mc changes, and mainly trying to help
repo maintainer to resolve conflicts in the tests quickly. A script is
proposed to help for the sorting
llvm#111769. Since these two files
are t16 only, it should not create conflicts in downstream branches
3. add -filetype=null to seperate stdout and stderr to avoid disordered
output from llvm-mc
