Now that all XModule SCSS is located in xmodule/static/sass,
it would make sense to co-locate the CSS there as well.
We also add a README to explain the purpose of this new folder.
In the future, we will move xmodule/js and xmodule/assets
into xmodule/static as well.

`xmodule_assets` generated a series of SCSS "entrypoint"
files, where each entrypoint file imported from the
SCSS "sources" in xmodule/css.
This process was more complicated up until very
recently (see PRs in issue linked below for more
context). Now that the process is simpler, though,
there is no reason to generate the SCSS entrypoints;
we can just commit them to the repository instead!
So, we go from this:
# GENERATED: SCSS entrypoints files for CMS
common/static/xmodule/descriptors:
AboutBlockStudio.scss
AnnotatableBlockStudio.scss
...
# GENERATED: SCSS entrypoints files for LMS
common/static/xmodule/modules:
AboutBlockPreview.scss
AnnotatableBlockPreview.scss
...
# VERSION CONTROLLED: SCSS source files
xmodule/css:
annotatable/...
capa/...
...
to this:
# VERSION CONTROLLED: All XModule SCSS
xmodule/static/sass:
# Source files
include:
annotatable/...
capa/...
...
# CMS entrypoint files
cms:
AboutBlockStudio.scss
AnnotatableBlockStudio.scss
...
# LMS source files
lms:
AboutBlockPreview.scss
AnnotatableBlockPreview.scss
...
Also, we are able to remove all SCSS-related logic from the
`xmodule_assets` script and from the `HTMLSnippet` class.
XModule JS assets still need processing, but we will address
those in a separate series of PRs.
