feat(search): Highlight search term This supersedes #10116. For the requested colored-output tests, this followed the pattern of the `fix` tests which just detects whether colored output is used or not. The `cache_messages` actually verify the output is colored but that is because it can just compare to a rustc call's output. Getting the colored output correct by hand in a test (with all of the resets) is a bit messy and would be brittle. This was done in an exercise in exploring ways to generalize colored output support in preparation for `cargo-add` doing some colored output as well. I converted all output calls to use this approach, even if coloring wasn't used, for consistency. I considered coloring the overflow message but decided to hold off on that for now (either a warning-yellow or a hint-gray). Fixes #9918

Describe the problem you are trying to solve
cargo searchappears to have a--coloroption which it doesn't use. Now not using it isn't the problem in particular, the lack of color which would be useful is.Describe the solution you'd like
I think it would be useful to add color the output to make it easier to see descriptions and versions.
