The behavior to return a list containing a single empty string when
provided an empty string is a behavior that absl inherited from legacy
code. However, the behavior expected by legacy code in Nix is the
behavior provided by the SkipEmpty option. Switch all calls to use
SkipEmpty, except for the call already using SkipWhitespace.

When tokenizeString was changed to absl::StrSplit, there was a behavior
change because tokenizeString on an empty string returned an empty
vector - which the derivation builder (and likely a bunch of other
stuff) was depending on. The canonical way of fixing this is by passing
absl::SkipEmpty() to the function - there may be other places we need to
fix this as well.
This commit also includes some opportunistic absl::StrFormats and
StrCats, because I was here anyway, but those have no semantic
difference.

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.
