Description
Currently const params are not lowered at all:
https://github.com/rust-analyzer/rust-analyzer/blob/aa91a0268bae6deda964a9fdfcbdbd2d8ca5802f/crates/hir_def/src/path/lower.rs#L177-L178
These kind of define bodies, so they come with all the goodies(and problems like local items) that other items like functions, statics and consts come with, and just like those they should ideally be lowered lazily.
