This reverts commit d382721cf8,
which seems to break edx-platform's ability to load the content of externally-
defined xblocks (e.g. lti_consumer) from course exports.
Previously, the built-in XBlocks (problem, video, etc) could be parsed
from pointer tag syntax, but externally-defined XBlocks (drag-and-drop,
ORA, etc.) could only be parsed from inline syntax. This is because the
built-in blocks have special parsing logic, defined in XmlMixin,
which is not available to external blocks.
This PR shifts the pointer tag parsing "up a level" such that the parent
blocks parse the pointer tag, regardless of whether the child is built-in
or external:
* vertical (aka unit)
* split_test (aka content experiment)
* itembank (aka problem bank)
* library_content (aka randomized legacy library)
The following parent blocks still lack support for external pointer-tag children;
we will fix this in a follow-up PR:
* randomize
* all externally defined container blocks

This has been a no-op for a long time anyway, since HierarchyMixin
has been explicitly mixed into XBlock for as long as I remember.

This function was only used by tests. It was breaking tests from the `xmodule`
package on the devstack because the dist.key of its entry_points is `open-edx`.
- Moving xmodule folder to root as we're dissolving sub-projects of common folder in edx-platform
- More info: https://openedx.atlassian.net/browse/BOM-2579
- -e common/lib/xmodule has been removed from the requirements as xmodule has itself become the part of edx-platform and not being installed through requirements
- The test files common/lib/xmodule/test_files/ have been removed as they are not being used anymore
