The prior use of gc_allocator meant that the btree nodes themselves were being collected. Additionally, have Attr (contains a Value) and Bindings explicitly inherit from gc, even though Bindings is always allocated under `new (GC)`.
Detected by running under GC_ENABLE_INCREMENTAL=1.

Implement the proto handler for AddToStore, which adds a nix path to the
store. This is implemented by adding a new (probably
soon-to-be-generalized) Source concretion that wraps a grpc ServerReader
for the stream of data we're receiving from the client - this is less
than ideal, as it's perpetuating the source/sink thing that's going on
and storing entire nars in memory, but is at the very worst an
incremental step towards a functioning nix that we can refactor in the
future.

Replace the custom, rather questionable base64 implementation with
absl::Base64{Une,E}scape. To make sure that the custom implementation
was doing the same thing I've also added a test covering
nix::Hash::to_string, which was one function that used it - the test
passed prior to the replacement, and continued to pass afterwards.
The previous base64Decode function threw an exception on failure - to
avoid going too far down the rabbit hole I've replicated that
functionality at all call sites, but this should be replaced with more
sensible error handling such as StatusOr eventually.

This is the shared object equivalent of builtins.exec, or a plugins

Plugins seem to not really be used anywhere (I can find one plugin

it will definitely be after we have a functioning Nix again.

* The output is not yet checked against the expected value, so the

* A handful of tests have been disabled as they are causing failures
that may be related to the DummyStore implementation.
Both of these will be addressed in followup commits, but there is
already some value in having the pure evaluation tests pass.

Implement the proto handler on the server side for
Worker::BuildDerivation. This includes several additions to the proto
which I had missed on the first pass, including the actual proto
definition for the Derivation itself and a few sequence number
reorderings which are fine because this is all provisional and not
deployed yet.
A couple things to note
- I implemented a couple constructors for nix classes that initialize
themselves based on their proto variants, which felt nice and didn't
end up causing any issues.
- I've made the conversions between the enum types in nix and in proto
explicit via switch statements rather than using a static_cast, out of
an abundance of caution that the error would get mismatched in the
future and we'd convert the wrong thing to the wrong thing - this is
verbose, but exceptionally future proof.
