GHS: Append ".gpj" to target name when generating build command

-- Add test demonstrating issue
-- In the case of executable targets the target name is usually the same as used in "-o filename"
   But for static libraries the target name is usually "-o libname.a"
   "gbuild.exe target" will build whatever target matches against even the output from the compiler or linker
   But the targets in "cmake --build . --target name" should be target names in CMakeLists.txt not the actual filenames
   So change the "name" to "name.gpj" so it matches the target name in CMakeLists.txt.

Fixes #15975
