Before this commit, `Parse`s for original file ended up two times in
salsa's db: first, when we parse original file, and second, when we
parse macro or a file.
Given that parse trees are the worst ofenders in terms of memory, it
makes sense to make sure we store them only once.
1368: Store referece instead of full token tree in tokenbuffer r=matklad a=edwin0cheng
This PR try to minimize the memory allocation in converting `SyntaxNode` to `TokenTree` by using reference isnteead of full token tree in `TokenBuffer`.
Note that the final goal is replace `TokenTree` with TokenBuffer such that there is no conversion between them.

1362: Introduce AST database r=matklad a=matklad
The idea here is to separate fragile bits which look into the syntax directly from robust bits which are safe across reparses. This uses the new `salsa::requires` featue

We use panics for cancellation, so we could trigger panic while
holding the solver. std::sync::Mutex will be poisoned as a result,
which and all further attempts to use solver (from other threads) will
panic as well.
This commit switches to parking_lot::Mutex which just unlocks on panic.

On CI, we remove this project's artifacts from ./target before caching
it. This way, cache never changes, because it only caches deps.
We do this approximatelly, and, together with our own tools crate, we
also remove itertools, which are used by some other deps. Given that
tools change rarely, let's just cache them?
