Rollup merge of #104012 - chenyukang:yukang/fix-103882-deli-indentation, r=petrochenkov
Improve unexpected close and mismatch delimiter hint in TokenTreesReader

Fixes #103882
Fixes #68987
Fixes #69259

The inner indentation mismatching will be covered by outer block, the new added function `report_error_prone_delim_block` will find out the error prone candidates for reporting.

Emit a hint for bad call return types due to generic arguments

When the return type of a function call depends on the type of an argument, e.g.

```
fn foo<T>(x: T) -> T {
    x
}
```

and the expected type is set due to either an explicitly typed binding, or because the call to the function is in a tail position without semicolon, the current error implies that the argument in the call has the wrong type.

This new hint highlights that the expected type doesn't match the returned type, which matches the argument type, and that that's why we're flagging the argument type.

Fixes #43608.
