`cast_possible_truncation` Suggest TryFrom when truncation possible

This fixes the last issues from https://github.com/rust-lang/rust-clippy/pull/9664 as the author seems to be inactive. The PR author was sadly kept during the rebase, due to the conflict resolution.

IDK if it's worth it do to a full review, I only added the last commit, everything else remained the same, besides a rebase.
