bitbake: doc: user-manual: remove mentions to BBVERSIONS

BBVERSIONS support was dropped in November 2016 in commit
0bb188f01e39 "ast: remove BBVERSIONS support".

Let's update the documentation to reflect this.

This was found by running:

git grep -hoP '^   :term:`\K\w+(?=`)' doc/bitbake-user-manual/bitbake-user-manual-ref-variables.rst | \
  xargs -I{} sh -c \
    "grep -Rq --include='*.py' --include='*.conf' --include='*.bbclass' --include='*.bb' --include='*.bbappend' --include='*.inc' \
      -w -E {}'_*(_[a-z]+[0-9a-z]*[a-z]+)*' || \
     echo {}"

-BitBake supports two features that facilitate creating from a single

+BitBake supports multiple incarnations of a recipe file via the

+The :term:`BBCLASSEXTEND` variable is a space separated list of classes used

--  ``BBVERSIONS``: This variable allows a single recipe to build
-   multiple versions of a project from a single recipe file. You can
-   also specify conditional metadata (using the
-   :term:`OVERRIDES` mechanism) for a single
-   version, or an optionally named range of versions. Here is an
-   example::
-
-      BBVERSIONS = "1.0 2.0 git"
-      SRC_URI_git = "git://someurl/somepath.git"
-
-      BBVERSIONS = "1.0.[0-6]:1.0.0+ 1.0.[7-9]:1.0.7+"
-      SRC_URI_append_1.0.7+ = "file://some_patch_which_the_new_versions_need.patch;patch=1"
-
-   The name of the range defaults to the original version of the recipe. For
-   example, in OpenEmbedded, the recipe file ``foo_1.0.0+.bb`` creates a default
-   name range of ``1.0.0+``. This is useful because the range name is not only
-   placed into overrides, but it is also made available for the metadata to use
-   in the variable that defines the base recipe versions for use in ``file://``
-   search paths (:term:`FILESPATH`).
