CMakeLists: Generate the cmCommands.cxx file.

Define the list of commands in the CMakeLists.txt file. List the
sources in the CMakeLib target, but mark them as HEADER_FILE_ONLY.
This has the effect that IDEs will show the files, though they
will not be built again.

Add a cmCommandsForBootstrap.cxx file for bootstrapping purposes.

Rename the cmExportLibraryDependencies file to match the common
pattern.
