build: commit XModule SCSS entrypoints of generating them

`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; for context, make sure you've seen:
 * #32288
 * #32289

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.
