[PATCH 2/3] Documentation/gpu: add some tables of contents to large documents

[Jani Nikula <jani.nikula@intel.com>]

Some of the GPU documentation pages are quite long, with various levels
of details. Add document internal tables of contents to the larger
documents to make them easier to navigate.

The index.rst in the sub-directories have toctrees, which provide
similar overviews.

Fix one missing newline at the end of drm-uapi.rst while at it,
primarily because rst should have it, and secondarily because my editor
rst mode refuses to save the file without it.
