1138: Add L_DOLLAR and R_DOLLAR r=matklad a=edwin0cheng

As discussion in issue https://github.com/rust-analyzer/rust-analyzer/issues/1132 and PR #1125 , this PR add 2 `Syntax::Kind` : `L_DOLLAR` and `R_DOLLAR` for representing `Delimiter::None` in mbe and proc_marco. By design, It should not affect the final syntax tree, and will be discard in `TreeSink`.

My original idea is handling these 2 tokens case by case, but i found that they will appear in every place in the parser (imagine `tt` matcher). So this PR only handle it in `Parser::do_bump` and `Parser::start`, although It will not fix the `expr` matcher executing order problem in original idea.

1105: [WIP] Implement ra_mbe meta variables support  r=matklad a=edwin0cheng

This PR implements the following meta variable support in `ra_mba` crate (issue  #720):

- [x] `path`
- [ ] `expr`
- [ ] `ty`
- [ ]  `pat`
- [ ] `stmt`
- [ ]  `block`
- [ ]  `meta`
- [ ] `item`

*Implementation Details*

In the macro expanding lhs phase, if we see a meta variable type, we try to create a `tt:TokenTree` from the remaining input. And then we use a special set of `ra_parser` to parse it to `SyntaxNode`.

Also fixes an error introduced by #1072 where something like `async move "foo"` in expression position would trigger the assertion in `block_expr`.

98cff6ecec Change parsing bounds in path_types
Now bounds inside a path are parsed as DYN_TRAIT_TYPE, previously they would be
parsed as `PATH_TYPE` followed by `TYPE_BOUND_LIST`.

Basically this means `Box<T + 'f>` is now parsed almost the same as
`Box<dyn T + 'f>` with the exception of not having the `dyn` keyword.

23fdc562bf Add new TYPE_BOUND_LIST and TYPE_BOUND syntax kinds
These are now used when parsing type bounds. In addition parsing paths inside a
bound now does not recursively parse paths, rather they are treated as separate
bounds, separated by +.

991: Use Marker argument for item parsers r=matklad a=pcpthm

Before doing this for expressions, I found that the pattern (Marker argument) should be applied to the item parsers because visiblity and modifiers are parsed in a separate function.

Fixed some parser bugs:
- Fix pub_expr: `pub 42;` was allowed.
- Fix incorrect parsing of crate::path: incorrectly parsed as `crate` as a visibility.

987: Refactor maybe_item to use Marker argument r=pcpthm a=pcpthm

As suggested at <https://github.com/rust-analyzer/rust-analyzer/pull/980#issuecomment-473659745>.
For expression paring functions, changing signature
- from `fn(&mut Parser) -> Option<CompletedMarker>` to `fn(&mut Parser, Marker) -> Result<CompletedMarker, Marker>`
- from `fn(&mut Parser) -> CompletedMarker` to `fn(&mut Parser, Marker) -> CompletedMarker`
is my plan.

983: support remainder assignment operator r=matklad a=JeanMertz

`%=` was returning errors for me, turns out it wasn't added as a valid assignment operation.

I'm not sure what the best location would be to add a test for this. Please let me know and I'll add one.
