72e61aa584 refactor(tvix): completely remove boehm gc
We have decided that leaking memory is a better fate than random,
non-debuggable memory corruption. Future CLs will begin changing
various fields to std::unique_ptr and std::shared_ptr.

It turns out that disabling the GC does not have disasterous impact.
The Nix evaluator only runs on the client CLI, never in any long-
running process. Even the REPL does not leak too badly under this
change, because it uses one EvalState for the duration of the REPL.

Building an explicitly tracing garbage collector is likely in the
future of this project, but that giant amount of work cannot be
done under a nix evaluator that is constantly crashing. We need to
restore development velocity here, and this is the best way we've
figured out to do it.

d1653533a6 test(tvix): Cover scanForReferences in a test
Aded a few test cases covering the scanForReferences function, which had
been accidentally broken in 976a36c (which is now partially-reverted).
As part of this, since the test needed to generate hashes for store
paths, the logic in MakeStorePath to compress a sha256 hash down to 20
bytes and convert it to base32 has been extracted to a member function
on the Hash class.

68b5306c56 feat(3p/nix): add --trace-file-access to nix-instantiate
This builds on edef's work with depot-scan by adding a dedicated

implementation, the checkSourcePath function.

f9df9b4733 fix(3p/nix): fix usage error of absl::Base64Unescape
The source and destination strings cannot be the same string - absl
will write to the destination in a streaming manner, causing the
source to become invalid.

In certain circumstances, the decompression thread could race ahead of the downloader thread and process the same chunk twice. Clear the data buffer while the lock is held to prevent this kind of incident.
