Allow the Package Registry to be disabled (#14849)

When a project is packaged for redistribution the local package
registries should not be updated or consulted.  They are for developers.

Add variables to disable use of package registries globally:

* CMAKE_EXPORT_NO_PACKAGE_REGISTRY that disables the export(PACKAGE)
  command
* CMAKE_FIND_PACKAGE_NO_PACKAGE_REGISTRY that disables the User Package
  Registry in all the find_package calls.
* CMAKE_FIND_PACKAGE_NO_SYSTEM_PACKAGE_REGISTRY that disables the
  System Package Registry in all the find_package calls.

Update documentation and unit tests.

build tree. In some cases, for example for packaging and for system
wide installations, it is not desirable to write the user package
registry. If the :variable:`CMAKE_EXPORT_NO_PACKAGE_REGISTRY` variable
is enabled, the ``export(PACKAGE)`` command will do nothing.
