Evaluate if running `miri` is useful for us

[dblnz]

Following a comment from PR #1072, we should investigate if we could run miri on Hyperlight sensitive areas to ensure we don't introduce any undefined behavior.

We might want to run miri with tests that deal w/ unsafe and accesses to memory. Miri does not support ioctls though, so that's something to watch out for.

Miri can only run small unit tests, so we would need some refactoring here. Might want to considering breaking this issues into sub-issues "mirifying" different parts of the codebase.
