Lint suggestion: Prefer use x::y; over use x::prelude::y;

If we don't want to treat "prelude" as a special symbol, then we could generalize it to prefer "sub-paths".

Is there anything particularly wrong with using the import from the prelude? Imo this is more of a style thing that would be better implemented in rustfmt or clippy in general.
This is a weak opinion, don't block the lint on this if others think it's useful.

@alice-i-cecile I see on Discord that you like this lint. Could you post some motivation?

[alice-i-cecile]

This is a "stylistic consistency" lint. It's helpful to reduce visual clutter and merge conflicts on imports. I also think that the reverse (prefer prelude) should be included. Clippy has a number of these, see clippy's absolute_paths lint for an analog.

I can definitely see the stylistic reasoning behind this, but I think for now it should be disabled by default.

1. RA usually auto-imports from the prelude, and I'm not sure if it's possible to disable this. This would make the warnings frequent and annoying.
2. This should probably be a feature of rustfmt, but I'm cool to implement it here for now.

[alice-i-cecile]

Yep, fully agree on disabled-by-default: I think that the whole style category should be.
