Simplify CMake per-source license notices Per-source copyright/license notice headers that spell out copyright holder names and years are hard to maintain and often out-of-date or plain wrong. Precise contributor information is already maintained automatically by the version control tool. Ultimately it is the receiver of a file who is responsible for determining its licensing status, and per-source notices are merely a convenience. Therefore it is simpler and more accurate for each source to have a generic notice of the license name and references to more detailed information on copyright holders and full license terms. Our `Copyright.txt` file now contains a list of Contributors whose names appeared source-level copyright notices. It also references version control history for more precise information. Therefore we no longer need to spell out the list of Contributors in each source file notice. Replace CMake per-source copyright/license notice headers with a short description of the license and links to `Copyright.txt` and online information available from "https://cmake.org/licensing". The online URL also handles cases of modules being copied out of our source into other projects, so we can drop our notices about replacing links with full license text. Run the `Utilities/Scripts/filter-notices.bash` script to perform the majority of the replacements mechanically. Manually fix up shebang lines and trailing newlines in a few files. Manually update the notices in a few files that the script does not handle.

Convert CMake non-find modules to BSD License This adds copyright/license notification blocks CMake's non-find modules. Most of the modules had no notices at all. Some had notices referring to the BSD license already. This commit normalizes existing notices and adds missing notices.

Keep cmake_minimum_required calls in sync with current version Update cmake_minimum_required calls in CMakeLists.txt in Modules and in CMakeLists.txt generated by other modules, so that they are always in sync with current CMake version.

Create FortranCInterface_VERIFY function This function builds a simple test project using a combination of Fortran and C (and optionally C++) to verify that the compilers are compatible. The idea is to help projects report very early to users that the compilers specified cannot mix languages.

FortranCInterface: Compile separate Fortran lib in VerifyC[XX] The Intel Fortran plugin for Visual Studio requires Fortran source files to be compiled in a separate target from C and C++ code. Compile the VerifyFortran.f source file in a separate library and link the main VerifyFortanC executable to it.

Fix FortranCInterface_VERIFY for non-C++ case The verification program entry point (main) is defined in a C source file, so the C compiler should be used to link when only Fortran and C are involved. The C++ compiler should still be used when the CXX option is enabled.
