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.
This small fix should improve rust-analyzer resopnsivness for
real-time operations like onEnter handling.
Turns out, salsa's validation can take hundreds of milliseconds, and,
in case no changes were made, it won't be triggering any queries.
Because we check for cancellation in queries, that means that
validation is not cancellable!
What this PR does is injecting check_canceled checks into validation,
by using salsa's event API, which wasn't meant to be used like this,
but, hey, it works!
Here's the onEnter handling before and after this change:

1337: Move syntax errors our of syntax tree r=matklad a=matklad
I am not really sure if it's a good idea, but `SyntaxError` do not really belong to a `SyntaxTree`. So let's just store them on the side?

Very simple approach: For each identifier, set the hash of the range
where it's defined as its 'id' and use it in the VSCode extension to
generate unique colors.
Thus, the generated colors are per-file. They are also quite fragile,
and I'm not entirely sure why. Looks like we need to make sure the
same ranges aren't overwritten by a later request?

1208: [WIP] Goto for Macro's r=matklad a=Lapz
Adds goto definition for macros. Currently only works for macros in the current crate ~~otherwise it panics~~. Proper macro resolution needs to be added for it to resolve macros in other crates.
Todo
- [X] Allow goto from macro calls
- [X] Fix panics
- [x] Add tests
