Rules is a new feature that replaces only/except and allow for finer grain
control on the workflow. With rules, we gain finer grain to pipeline and merge
request pipelines.
The windows runner has become a bit unstable lately, might be
due to some recent update. It frequently timeouts while waiting
to pick up a job or sometimes it goes missing in the middle of a job.
This is where the WINEPREFIX is now in Cerbero. This used to be
share/wine, but was moved to var/tmp/wine for clarity. It was causing
two problems:
1. The size of these generated files are ~1GB, which were ~500MB after
tar.gz, and they were completely useless since they can just be
regenerated by Wine the next time it's run. Let's not waste egress
bandwidth.
2. Random build failures because wineserver and associated processes
would not always exit before we started tarring up the prefix, then
write to the directory on exit while tar was reading the directory
causing `tar -czf` to fail:
```
$ tar -C ${CERBERO_HOME} -czf $CERBERO_DEPS build-tools build-tools.cache dist/${ARCH} ${ARCH}.cache
tar: build-tools/share/wine: file changed as we read it
Uploading artifacts...

```
This is slightly weird, cause I am not sure what causes the clone
to be there, since gitlab-runner supposedly always either use a
clean volume or at least runs git clean on the existing ones.
But its there and so we have to deal with failures like so

That job was the slowest, now each jobs takes about 12 minutes, which
makes it slightly faster then msys2 jobs, and sometime iOS due to low
bandwidth and low availibility of OSX runners.
CCache tends to consume a lot of space which taxes heavily some
of the shared runners. Limit the mahcines the job can run
to those were we can ensure they will not have issues with
the storage.

This is not bash, but powershell, hue hue hue
Rebuild the windows docker image against the current ltsc [1]
of server 2019. This requires moving some of the msys setup
to the runner job cause it causes docker build to hang
Switch the job tags so they now use the 1809 runner, instead
of 1607.
Tweak the PATHs in the msys job so bash doesn't complain about
slashes..
Lastly, increase the timeout of the windows jobs, as msys2
installs its deps at runtime
[1] https://docs.microsoft.com/en-us/windows-server/get-started-19/servicing-channels-19
In case a build gets stuck for whatever reason,
happens from time to time on windows,
try to baild out quickly.
For cerbero builds, set the timeout to 3h which
according to the docs should also be able to
override the project defined timeout
