  [Clang][LoongArch] Support target attribute for function (#140700)

This adds support under LoongArch for the target("..") attributes.

The supported formats are:
- "arch=<arch>" strings, that specify the architecture features for a
function as per the -march=arch option.
- "tune=<cpu>" strings, that specify the tune-cpu cpu for a function as
per -mtune.
- "<feature>", "no-<feature>" enabled/disables the specific feature.
