Only libexpr depends on the garbage collector, specifically only
instantiations of EvalState actually require the GC to be initialised.
Rather than always starting it for the whole program, even if it is
not needed, this change moves the GC initialisation into libexpr,
guarded by absl::call_once.
This should make it possible to run the nix daemon without the garbage
collector interfering, granted that things are correcty separated and
the daemon does not actually invoke the evaluator.
Based on my investigation so far, the daemon logic itself does not
require libexpr to be present at all - so I think it is safe - but the
current monobinary might have some tricks up its sleeve that will
cause problems for us. We can deal with those if they arise.

This is the easiest way to get the checks up and running for now, but
we will probably want to separate out things like this into a separate
build step in the future.

Unfortunately, to guarantee correct behaviour of some evaluation (!)
tests, addToStore needs to actually check whether passed in source
files exist and fail appropriately.
There is a chance that the dependency on this behaviour is actually a
bug in the upstream test suite, but my attempts at finding out more
about this from, say, the git history have so far been unsuccessful.

This store implementation is required in all unit tests that use the
evaluator.

Configures the CMake build to load & run the GoogleTest tests.
I (grfn) also updated this to get the tests running as part of the nix
derivation, which required defining our own manual configurePhase and
installCheckPhase, rather than depending on the one provided by stdenv.
Not doing this would cause cmake to attempt to *run* the tests as part
of the buildPhase, which wouldn't work because the dynamic libraries
hadn't been put into a place where the test executables knew where to
find them. We're not sure *why* this fixes it, and for some reason
fixing this also breaks the automatic behavior of nixpkgs of passing
-j$NIX_BUILD_CORES -l$NIX_BUILD_CORES to make, but that's eaasy enough
to fix manually in a preBuild
