Move cmake plugin to bst-plugins-experimentalcoldtom/move-cmake

It was agreed on the mailing list to move all plugins to a single
repository, before moving them into domain-specific repositories. As
a result it seems reasonable to move everything to the
bst-plugins-experimental repo as this stepping stone, rather than
creating a whole new repo.

This commit starts the process of moving things over by moving only the
cmake plugin to bst-plugins-experimental, and altering the tests to
reflect the new location.

-cmake - CMake build element
-===========================
-This is a :mod:`BuildElement <buildstream.buildelement>` implementation for
-using the `CMake <https://cmake.org/>`_ build system.
-
-You will often want to pass additional arguments to the ``cmake`` program for
-specific configuration options. This should be done on a per-element basis by
-setting the ``cmake-local`` variable.  Here is an example:
-
-.. code:: yaml
-
-   variables:
-     cmake-local: |
-       -DCMAKE_BUILD_TYPE=Debug
-
-If you want to pass extra options to ``cmake`` for every element in your
-project, set the ``cmake-global`` variable in your project.conf file. Here is
-an example of that:
-
-.. code:: yaml
-
-   elements:
-     cmake:
-       variables:
-         cmake-global: |
-           -DCMAKE_BUILD_TYPE=Release
-
-Here is the default configuration for the ``cmake`` element in full:
-
-  .. literalinclude:: ../../../src/buildstream/plugins/elements/cmake.yaml
-     :language: yaml
-
-See :ref:`built-in functionality documentation <core_buildelement_builtins>` for
-details on common configuration options for build elements.
