Intead of passing around the output of the config generator program,
which consists of paths joined by a separator we can have the generator
simply produce an extra file containing those paths.
This commit only implements the new approach for the core plugins, as
this was needed to avoid spurious meson rebuilds when the pre-commit
hook regenerates the core plugins_cache.

* Move the exported PATH variables into a script so
we can source it in all the wrapper scripts.
* Add a guard to only copy over the cache when the
SUBPROJECTS_CACHE_DIR variable is set, which only
happens on CI by default
* Make it possible to run the scripts with default
values for some of the variables, like WERROR and MESON_ARGS.

This dehardcodes the builddir the scripts use, and allows
us to pass it as a cli argument.
It also allows us to pass the test stuite string as an
arg for test.sh
This makes the scripts a bit more usable for local development
as well.
