[CMake] Fix install failure with CMAKE_SLANG_FRONTEND_ENABLED enabled (#7437) 

Slang compiler relies on the third-party libraries like unordered_dense and fmt
library. The fmt library provides two ways to integrated it:
  1.Headers-only
  2.Seperately compiled
The main purpose of this commit is to avoid installation failure of CIRCT project due
to finding fmt header file in wrong path which is in circt `include` directory when
CMake_slang_Frontend_enabled is turned on. We hope to not install header files coming
from fmt library.
