feat: render patterns in params for hovering

[roife]

Fix #17858

This PR introduces an option to hir-def/src/body/pretty.rs to render the result as a single line, which is then reused for rendering patterns in parameters for hovering.

The only issue now is that we are rendering fn test(Point { x, y }: Point) {} as fn test(Point { x: x, y: y }: Point) {}. Can we just modify pretty.rs, although this might change the output of hir_view? 👀
