Add `WriteableScore` bindings impl for `MultiThreadedLockableScore`

In 56b07e52aabdaca521987e765f1fa864966a5d49 we made
`MultiThreadedLockableScore` fully bindings-compatible. However, it
did not add a `WriteableScore` implementation for it. This was an
oversight as it is a `WriteableScore` in Rust and needs to be for
use in other parts of the API.

Here we add the required impl in a way that the bindings generator
is able to handle it and add conversion utilities.
