[AMDGPU][test] fix the error case in update_mc_test_check script (#112731)

update_mc_test_check script handle the "error case testline" wrong in
three cases:

1. when user select "--llvm-mc-binary" with a path, the script does not
add "not" on top of the "--llvm-mc-binary" and thus getting non-zero
exit code and failed.
2. When "not" is presented in runline while not all testlines are
expected to fail, the script need to check if the "not" is needed when
it execute llvm-mc line by line. Otherwise the script will fail on
testline which is passing.
3. When there are multiple runlines, the error checkline need to use
correct line offset for "[[LINE-X]]"

This patch solve these three issues

[AMDGPU][test]added unique and sort options for update_mc_test_check script (#111769)

add a unique and a sort option to the update_mc_test_check script.

These mc asm/dasm files are usually large in number of lines, and these
lines are mostly similar to each other. These options can be useful when
maintainer is merging or resolving conflicts by making the file
identifical

Also fixed a small issue in asm/dasm such that the auto generated header
line is
1. asm using ";" instead of "//" as comment marker
2. dasm using ";" instead of "#" as comment marker

added a script to update llvm-mc test file (#107246)

Added a script to update the test file generated by llvm-mc binary. The
script accepts .s and .txt for asm and dasm.

For mc test I am targetting there is no function name which can be used
as a key, thus no clear mapping between input and output. The script
assumes the test are always line-by-line and it update the output marker
for each test line-by-line.
