gnu: python-brotli: Move to python-compression and switch to pyproject.

Fixes gnu/gnu#1730

python-brotli does not benefit from being inherited from brotli, it's
built from scratch, this change moves it to python-compression as a
stand along package, a collection of Python bindings and swap build
system to pyproject.

* gnu/packages/compression.scm (python-brotli, python-google-brotli):
Move from here ...
* gnu/packages/python-compression.scm: ... to here.
* gnu/packages/django.scm: Add python-compression module.
* gnu/packages/fonts.scm: Likewise.
* gnu/packages/gnome.scm: Likewise.
* gnu/packages/video.scm: Likewise.
