Make multiple improvements to the existing workflows:
- create a shared custom action to deal with version number tracking
and generation;
- use this action to add the branch name to the version for pull
request builds;
- create a shared workflow for all debian-ish builds to avoid re-use
by copy / paste;
- remove potential security risks by eliminating the use of
pre-evaluated expressions (`${{ ... }}`) inside scripts;
- update outdated GitHub action versions;
- improve the consistency by renaming scripts acording to have a `.sh`
extension;
- improve naming of generated artefacts for pull requests to include
the correct version.
@dirkh: Unfortunately this is potentially going to break builds when it is
merged, as there is no good way to 'test' a merge build short of
merging.
We'll just have to deal with the fallout of it in a follow-up pull
request.

Add a GitHub action that builds the docker image to run builds for the
Windows (MXE) version of Subsurface.
Also update the MXE image Dockerfile to the latest version of MXE, and
add a patch to use a current version of mdbtools.
Configure GitHub actions that do not build docker images to not trigger
on changes to the contents of `scripts/docker/`.
