Compiler-rt's assembly files do not get the GCS properties when compiled with `-mbranch=protection=standard` with clang-21
dump of a object generated from .S file says
```
Properties: AArch64 feature: BTI, PAC
````
where as objects from .c files have
```
Properties: AArch64 feature: BTI, PAC, GCS
```
This causes shared objects linking with `-rtlib=compiler-rt` ends up with mssed GCS property as well. If we choose `-rtlib=libgcc` then the property gets into shared libraries correctly.
We need to implement GCS support into needed asm files in compiler-rt for aarch64
