feat: always show list of features on cargo add

[motorailgun]

Partially solves #15524

What does this PR try to resolve?

Currently, cargo shows list of features available for the package added only when features specified correctly. In turn, if the features specified by cargo add --features doesn't exist (at least for the version specified in Cargo.toml), it just bails with "unrecognized feature(s)" error.

This PR modifies the timing of print_dep_table_msg() so that it's always called.

The changes of UI can be observed by peeking the modified SVGs. I think those changes make sense, however there might be different opinions.

Thank you for the fix!

Could you squash these two commits into one commit? By doing so we can ensure every commit passes CI, and git bisect would be a bit easier to conduct.

Thank you for reviewing! Just squashed and pushed.

#15438 added the "similar feature" messages and the lists of disabled and enabled features that are showcased in these error messages. We even customized the displaying of those specifically for errors (collapsing enabled features while the regular display will collapse disabled features).

So this feels a bit redundant to show the feature list. Is there a reason you feel we should do both?

FYI our contrib docs recommend opening issues first so we can discuss these things before implementing so we know what direction to implement and avoid you going in a direction we might not end up going with

Oops I somehow didn't notice that. I thought the "as of v x.x.x" part gives better insights in cases like the issue I mentioned, however it's undeniable that this feels too redundant.

And I'm sorry about discussion part - I hurried too much to do something; I should have talked on the issue beforehand.

Closing this PR, thanks for taking your time to review!
