bootstrap: Don't pass `Kind` to some places that don't need it The current CLI step's `Kind` was being passed deep into some selector-matching code that doesn't seem to actually need it. It seems that the kind associated with a step's `ShouldRun` paths/aliases always comes from that step, so proceeding to compare it against the step's kind later can never fail and doesn't achieve anything. As far as I can tell, this is a relic of rust-lang#91965 that (due to subsequent changes) doesn't do anything useful and also doesn't make a lot of conceptual sense. This PR therefore removes the `Kind` parameter from `PathSet::check`, and removes the `Kind` field from `TaskPath`. Touching `TaskPath` causes a lot of churn in snapshot tests, but there don't seem to be any changes in actual behaviour.

rustc_data_structures: Cleanup jobserver initialization In the past the initialization was more complicated, with two stages for "unchecked" and "checked" `jobserver::Client`. Now everything can just be merged into a single function.

How to interpret the job duration changes?

Job durations can vary a lot, based on the actual runner instance
that executed the job, system noise, invalidated caches, etc. The table above is provided
mostly for t-infra members, for simpler debugging of potential CI slow-downs.
