  -----------
  [clang][LoongArch] Ensure `target("lasx")` implies LSX support (#153542)

Currently, `__attribute__((target("lasx")))` does not automatically
enable LSX support, causing Clang to fail with `-mno-lsx`. Since
LASX depends on LSX, enabling LASX should implicitly enable LSX to
avoid clang error.
    
Fixes #149512.

Depends on #153541
