2615: Fix wrong path parsing for macro call in pattern position r=edwin0cheng a=edwin0cheng

The parser incorrectly insert a `PathPat` inside `MacroCall` syntax node when parsing inside a pattern position, for example : 

```rust
let foo!() = 0;
```

become:

```
 MACRO_CALL@[60; 66)
    PATH_PAT@[60; 63)     <------------- It should not exist
      PATH@[60; 63)
        PATH_SEGMENT@[60; 63)
          NAME_REF@[60; 63)
            IDENT@[60; 63) "foo"
    EXCL@[63; 64) "!"
    TOKEN_TREE@[64; 66)
      L_PAREN@[64; 65) "("
      R_PAREN@[65; 66) ")"
```

This PR fix this bug and add some test to make sure goto-defintion works for macro inside pattern.
