try_compile: consistently add language properties

It was very easy to forgot to add all the possible language
properties that try_compile might need. Refactored the code
to make it harder to skip flags.

This changes adds the missing language properties for
the CUDA, Fortran, OBJC, OBJCXX, and Swift languages:

- CMAKE_<LANG>_COMPILER_EXTERNAL_TOOLCHAIN
- CMAKE_<LANG>_COMPILER_TARGET
- CMAKE_<LANG>_LINK_NO_PIE_SUPPORTED
- CMAKE_<LANG>_PIE_SUPPORTED
