Rename CMake target 'executorch' to 'prim_ops_lib' for clarity

- Renamed executorch target to prim_ops_lib in CMakeLists.txt
- Added executorch as an alias for backward compatibility
- Updated executorch-config.cmake to use prim_ops_lib
- Removed redundant manual target_link_options_shared_lib calls in examples
- Updated documentation to reflect the new target name
