This makes Gid the same as the one in storage/v2. Before they can be
merge into one implementation, we probably want to have a similar
transition for remaining ID types.

Summary:
Dump executable used to use C++ bolt api for connecting to the server.
However, this is currently not efficient enough because it fetches entire data at once.
We switched to C api libmgclient which supports streaming of data.

Summary:
Split up `process-file` so that looking at the generated code for an LCP form is
easier from the REPL.
`process-lcp`, `generate-hpp` and `generate-cpp` now perform the generation of
C++ code, but take a list of "C++ elements" (the results of LCP forms) as input
and write their output to streams. They do no reading/evaluating of LCP forms of
their own.
`read-lcp` and `read-lcp-file` are used to read and evaluate a stream of LCP
forms. The latter is a specialized version for file streams which also reports
the position of the form within the file when an error happens.
`process-lcp-string` and `process-lcp-file` are convenient wrappers around the
main functionality that take a string (file) and output to strings (files).
Using `read-lcp` and `read-lcp-file` they process LCP forms and pass them off to
`process-lcp` for code generation.

Summary:
Implemented a simple dump executable which runs `RETURN dump()` on the database using Bolt protocol.
The `dump()` function returns a list of openCypher queries needed for database reconstruction (note: in the future we should use more appropriate method that supports streaming of data).

Summary:
TypeInfo will be needed for upcoming serialization via SLK. This diff
changes the already defined TypeInfo by removing the reliance on
capnp::typeId calls. The struct itself is now in utils.
Hopefully, this shouldn't break our RPC stack due to new ID generation.

This should allow us to more easily decouple the code which should be
open sourced. Unfortunately, the downside of this approach is that we
cannot rely on virtual calls to dispatch the serialization to correct
