Get the artifact cache from the context instead.

The artifact cache backend does not affect build outputs and we anyway
no longer have pluggable artifact cache backends. This hardcodes
CASCache instead of removing the entry completely to avoid cache key
changes.

This changes CASCache from a subclass to a delegate object of
ArtifactCache. As the lower layer, CASCache no longer deals with
elements or projects.

Fixes #659.

Split up artifact cache and CAS cache

This removes the `_instance` on the platform object that we use
for caching and not recreating the object everytime at the start
of every test.

This is to ensure our tests share the least amount of state.

The performance penalty is from 2 to 5% accross the whole test suite.
The readings were done 5 times for each before and after the change
and on the same computer.

We need to supress the brwap version caching for it to work.

This caching leaks for every test but removing it every time seems
too prohibitive, given that, normally, the bwrap version would not
change.

On a fedora 29 laptop, the performance degradation was around 5-10%
over the whole test suite if used globally.
