Summary: Currently if rust-project emits a malformed `DiscoverProjectData`, rust-analyzer will silently ignore it. I want to change this in rust-lang/rust-analyzer#19684, but we need to first ensure that rust-project only emits these events and not other logs. Currently, all tracing events are emitted by the `ProgressLayer`. This diff makes it so only events with an explicit `kind` are emitted.

Currently we silently fail if the line can be parsed as json but not as
DiscoverProjectData. That means if the discover command emits a malformedDiscoverProjectData, project discovery will never finish, and rust-analyzer becomes unusable. Instead, return an error if the line isn't a validDiscoverProjectDataso the discovery process fails and the error is correctly reported.
