This commit adds the skeleton of a new set of documentation for
`wasmtime` in the existing `docs` directory. This documentation is
organized and compiled with [mdbook] which the Rust project uses for
most of its own documentation as well. At a previous meeting we
brainstormed a rough skeleton of what the documentation in this book
would look like, and I've transcribed that here for an example of how
this is rendered and how it can be laid out. No actual documentation is
written yet.
This commit also additionally adds necessary support to auto-publish
both this book documentation and API documentation every time a commit
is pushed to the `master` branch. All HTML will be automatically pushed
to the `gh-pages` branch so long as the CI passes, and this should get
deployed to https://cranestation.github.io/wasmtime.
I've done a few dry-runs and I think this'll all work, but we'll likely
tweak a few things here and there after running this through CI to make
sure everything looks just as we'd like. My hope though is that after
this lands we can start actually filling out all the documentation and
being able to review it as well.
