Add a `Fortran_COMPILER_LAUNCHER` target property like those added for C
and CXX by commit v3.4.0-rc1~450^2 (Add options to launch the compiler
through tools like ccache or distcc, 2015-06-04) and CUDA by commit
v3.10.0-rc1~531^2 (CUDA: Add option to run the compiler through launcher
tools, 2017-06-09).
Fixes: #17499

Create a <LANG>_COMPILER_LAUNCHER target property (initialized by a
CMAKE_<LANG>_COMPILER_LAUNCHER variable) to specify a compiler launcher
tool. This will supersede the CMAKE_<LANG>_COMPILER_ARG1 approach to
using such tools. The old approach set CMAKE_<LANG>_COMPILER to the
launcher tool while the new approach leaves this variable set to the
actual compiler.
Implement this property for Makefile and Ninja generators. It cannot be
implemented for VS or Xcode generators as the IDE build tools offer no
such hooks.
