Rust: Add encoder/decoder tests

Rust: Add encoder/decoder tests

Uses the validation input test parser library in order to automate
running tests on "good" inputs to the mojom encoding and decoding
frameworks in the Rust bindings. Included is Rust code generated by
the Mojom code generator (to be added in a later CL) for
validation_test_interfaces.mojom, which is then used in the tests.

These are passing tests for the Mojom encoding/decoding framework in Rust based
on the "golden" files. The only test cases missing (in tests/encoding.rs) are
the versioning tests and one test for unknown enums.

mojom_validation.rs is a generated file that is 2000+ lines long; I don't
reasonably expect that to be reviewed, but it stands as the most recent version
of what the code generator outputs and is necessary for the tests against the
"golden" files to run.

Just to make sure, if you intentionally break something somewhere tests start
failing, right?

File mojo/public/rust/tests/util/mojom_validation.rs (right):

https://codereview.chromium.org/2213563002/diff/120001/mojo/public/rust/tests...
mojo/public/rust/tests/util/mojom_validation.rs:1: //! This file was
auto-generated by the Rust bindings generator.
I'll take your advice and trust the generator did the right thing :)

Haha, yes, I made sure of that. When they first started working I broke some
stuff to make sure it wasn't just a no-op or something.
