Implement Chalk's debug methods using TLS
Chalk now panics if we don't implement these methods and run with CHALK_DEBUG, so I thought I'd try to implement them 'properly'. Sadly, it seems impossible to do without transmuting lifetimes somewhere. The problem is that we need a `&dyn HirDatabase` to get names etc., which we can't just put into TLS. I thought I could just use `scoped-tls`, but that doesn't support references to unsized types. So I put the `&dyn` into another struct and put the reference to *that* into the TLS, but I have to transmute the lifetime to 'static for that to work.
