Rollup merge of #66913 - VirrageS:help-self, r=varkor,Centril 
Suggest calling method when first argument is `self`

Closes: #66782

I've explored different approaches for this MR but I think the most straightforward is the best one.

I've tried to find out if the methods for given type exist (to maybe have a better suggestion), but we don't collect them anywhere and collecting them is quite problematic. Moreover, collecting all the methods would require rewriting big part of the code and also could potentially include performance degradation, which I don't think is necessary for this simple case.

b26ddb8af3 Point at local similarly named element and tweak references to variants 
Point at the span for the definition of ADTs internal to the current
crate.

Look at the leading char of the ident to determine whether we're
expecting a likely fn or any of a fn, a tuple struct or a tuple variant.

Turn fn `add_typo_suggestion` into a `Resolver` method.

Improve message when attempting to instantiate tuple structs with private fields

Fixes #58017, fixes #39703.

```
error[E0603]: tuple struct `Error` is private

   |                ^^^^^

   = note: a tuple struct constructor is private if any of its fields is private
