This commit improves the diagnostic emitted when a tuple struct is being
constructed which has private fields so that private fields are
labelled and the message is improved.

This fixes an issue with the following sample:
mod foo {
mod inaccessible {
pub struct X;
}
pub mod avail {
pub struct X;
}
}
fn main() { X; }
Instead of suggesting both `use crate::foo::inaccessible::X;` and `use
crate::foo::avail::X;`, it should only suggest the latter.
It is done by trimming the list of suggestions from inaccessible paths
if accessible paths are present.
Visibility is checked with `is_accessible_from` now instead of being
hard-coded.

Some tests fixes are trivial, and others require a bit more explaining,
here are my comments:
src/test/ui/issues/issue-35675.stderr: Only needs to make the enum
public to have the suggestion make sense.
src/test/ui/issues/issue-42944.stderr: Importing the tuple struct won't
help because its constructor is not visible, so the attempted
constructor does not work. In that case, it's better not to suggest it.
The case where the constructor is public is covered in `issue-26545.rs`.

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.

Make the spacing between the code snippet and verbose structured
suggestions consistent with note and help messages.
