ac798e1f7c Implement syntax highlighting for format strings 
Detailed changes:
1) Implement a lexer for string literals that divides the string in format specifier `{}` including the format specifier modifier.
2) Adapt syntax highlighting to add ranges for the detected sequences.
3) Add a test case for the format string syntax highlighting.

5e5eb6a108 Align grammar for record patterns and literals 
The grammar now looks like this

   [name_ref :] pat

7a39bc3ba2 Make records grammar more orthogonal 
We used

  name [: expr]

grammar before, now it is

  [name :] expr

which makes things simpler

af04d45d32 Change missing impl assist to use todo!() instead of unimplemented() 
todo!() "Indicates unfinished code" (https://doc.rust-lang.org/std/macro.todo.html)

Rust documentation provides further clarification:

> The difference between unimplemented! and todo! is that while todo!
> conveys an intent of implementing the functionality later and the
> message is "not yet implemented", unimplemented! makes no such claims.

todo!() seems more appropriate for assists that insert missing impls.

74e3b48806 Parse correctly fn f<T>() where T: Fn() -> u8 + Send {} 
We used to parse it as T: Fn() -> (u8 + Send), which is different from
the rustc behavior of T: (Fn() -> u8) + Send

68196ccc10 Add AstElement trait, generate tokens, support tokens in enums 
- Adds a new AstElement trait that is implemented by all generated
  node, token and enum structs

- Overhauls the code generators to code-generate all tokens, and
  also enhances enums to support including tokens, node, and nested
  enums

da091b1303 Migrate tests .txt -> .rast 
The sytax tree output files now use .rast extension
(rust-analyzer syntax tree or rust abstract syntax tree
(whatever)).
This format has a editors/code/ra_syntax_tree.tmGrammar.json declaration
that supplies nice syntax highlighting for .rast files.

da8eb29a2f Macro patterns are not confused with expressions. 
We treat macro calls as expressions (there's appropriate Into impl),
which causes problem if there's expresison and non-expression macro in
the same node (like in the match arm).

We fix this problem by nesting macor patterns into another node (the
same way we nest path into PathExpr or PathPat). Ideally, we probably
should add a similar nesting for macro expressions, but that needs
some careful thinking about macros in blocks: `{ am_i_expression!() }`.
