Create new lint option_map_or_err_ok

[GuillaumeGomez]

Fixes #10045.

For the following code:

let opt = Some(1);
opt.map_or(Err("error"), Ok);

It suggests to instead write:

let opt = Some(1);
opt.ok_or("error");

Applied suggestions and simplified code. Like I said, I'll send a follow-up for my previous lint as well.
