bors 23a1280106 Auto merge of #16137 - unexge:complete-macros-in-macro-use, r=Veykril 
Complete exported macros in `#[macro_use($0)]`

Closes https://github.com/rust-lang/rust-analyzer/issues/15657.

Originally added a test case for incomplete input:
```rust
#[test]
fn completes_incomplete_syntax() {
    check(
        r#"
//- /dep.rs crate:dep
#[macro_export]
macro_rules! foo {
    () => {};
}

//- /main.rs crate:main deps:dep
#[macro_use($0
extern crate dep;
"#,
        expect![[r#"
                ma foo
            "#]],
    )
}
```

but couldn't make it pass and removed it 😅 Our current recovering logic doesn't work for token trees and for this code:
```rust
#[macro_use(
extern crate lazy_static;

fn main() {}
```

we ended up with this syntax tree:
```
SOURCE_FILE@0..53
  ATTR@0..52
    POUND@0..1 "#"
    L_BRACK@1..2 "["
    META@2..52
      PATH@2..11
        PATH_SEGMENT@2..11
          NAME_REF@2..11
            IDENT@2..11 "macro_use"
      TOKEN_TREE@11..52
        L_PAREN@11..12 "("
        WHITESPACE@12..13 "\n"
        EXTERN_KW@13..19 "extern"
        WHITESPACE@19..20 " "
        CRATE_KW@20..25 "crate"
        WHITESPACE@25..26 " "
        IDENT@26..37 "lazy_static"
        SEMICOLON@37..38 ";"
        WHITESPACE@38..40 "\n\n"
        FN_KW@40..42 "fn"
        WHITESPACE@42..43 " "
        IDENT@43..47 "main"
        TOKEN_TREE@47..49
          L_PAREN@47..48 "("
          R_PAREN@48..49 ")"
        WHITESPACE@49..50 " "
        TOKEN_TREE@50..52
          L_CURLY@50..51 "{"
          R_CURLY@51..52 "}"
  WHITESPACE@52..53 "\n"
```

Maybe we can try to parse the token tree in `crates/ide-completion/src/context/analysis.rs` but I'm not sure what's the best way forward.
