Pull Request Overview

This PR refactors CMake build configuration across the OCCA project. It splits the C and Fortran APIs into separate shared libraries (c_api and fortran_api), reformats all target_sources() and target_link_libraries() calls to use multi-line format for improved readability, and updates linking dependencies throughout the codebase.

Key changes:

• Created separate c_api and fortran_api shared libraries
• Reformatted all CMake function calls to use consistent multi-line style
• Updated all examples and tests to link against the new library targets
