Auto merge of #130778 - flip1995:clippy-subtree-update, r=Manishearth

Clippy subtree update

r? `@Manishearth`

Really delayed sync (2 1/2 weeks), because of a `debug_assertion` we hit, and I didn't have the time to investigate earlier.

It would be nice to merge this PR with some priority, as it includes a lot of formatting changes due to the rustfmt bump.

Include Cargo.lock update due to Clippy version bump and ui_test bump in Clippy.

Cargo.lock
