fix [`manual_flatten`] help texts order
fixes #8948
Whenever suggestion for this lint does not fit in one line,
legacy solution has some unexpected/unhandled behavior:
lint will then generate two help messages which seem to be shown in the wrong order.
The second help message in that case will contain the suggestion.
The first help message always refers to a suggestion message,
and **it should adapt** depending on the location of the suggestion:
- inline suggestion within the error/warning message
- suggestion separated into a second help text
This is my first contribution here, so I hope I didn't miss anything for creating this PR.

Add `repeated_where_clause_or_trait_bound` lint
I thought I would try and scratch my own itch for #8674.
1. Is comparing the `Res` the correct way for ensuring we have the same trait?
2. Is there a way to get the spans for the bounds and clauses for suggestions?
I tried to use `GenericParam::bounds_span_for_suggestions` but it only gave me an empty span at the end of the spans.
I tried `WhereClause::span_for_predicates_or_empty_place` and it included the comma.
3. Is there a simpler way to get the trait names? I have used the spans of the traits because I didn't see a way to get it off the `Res` or `Def`.
changelog: Add ``[`repeated_where_clause_or_trait_bound`]`` lint.

Lint simple expressions in `manual_filter_map`, `manual_find_map`
changelog: Lint simple expressions in [`manual_filter_map`], [`manual_find_map`]
The current comparison rules out `.find(|a| a.is_some()).map(|b| b.unwrap())` because `a` being a reference can effect more complicated expressions, this adds a simple check for that case and adds the necessary derefs
There's some overlap with `option_filter_map` so `lint_filter_some_map_unwrap` now returns a `bool` to indicate it linted
the two loops did practically the same, only the type were different (&&
vs &), so I used `copied` to convert `&&` and chained them together.
Instead of parsing the trait info manually, I use the already provided
method `get_trait_info_from_bound`.
Also, instead of using manual string writing, I used `join` by
`itertools`.
