2318: Fix panic when use `Expand Macro` on `assert_eq` r=matklad a=edwin0cheng
The cause of this [bug](https://github.com/rust-analyzer/rust-analyzer/pull/2291#issuecomment-555651542) is, when calling `SourceAnalyzer::expand` when an `ast::MacroCall` which is outside of `SourceAnalyzer::node`.
Note that if we use a node in `SourceAnalyzer::new` with a `MacroFile` file id, the resolver inside `SourceAnalyzer` still will not work properly. Another PR will need to fix it.

2325: Next gen IDs for functions r=matklad a=matklad
The current system with AstIds has two primaraly drawbacks:
* It is possible to manufacture IDs out of thin air.
For example, it's possible to create IDs for items which are not
considered in CrateDefMap due to cfg. Or it is possible to mixup
structs and unions, because they share ID space.
* Getting the ID of a parent requires a secondary index.
Instead, the plan is to pursue the more traditional approach, where
each items stores the id of the parent declaration. This makes
`FromSource` more awkward, but also more correct: now, to get from an
AST to HIR, we first do this recursively for the parent item, and the
just search the children of the parent for the matching def

This commit implements a general truncation framework for HirFormatter
that keeps track of how much has been output so far. This information
can then be used to perform truncation inside the language server,
instead of relying on the client.
Initial support is implemented for truncating types hints using the
maxInlayHintLength server config option. The existing solution in the
VSCode extension has been removed in favor of letting the server
truncate type hints.
