`detail` and `macro` weren't adding any info.

i broke this in the previous commit; and metrics never worked until i switched from `execute_cli` to build

The CSS uses an inconsistent mix of both. This commit switches
it to always use `src`.

Since the directory that contains source files is called `src`,
it makes sense to name the scripts that way, too.

This is a separate commit to keep Git happy.

Structurally normalize in selection

We need to do this because of the fact that we're checking the `Ty::kind` on a type during selection, but goals passed into select are not necessarily normalized.

Right now, we're (kinda) unnecessarily normalizing the RHS of a trait upcasting goal, which is broken for different reasons (rust-lang#113393). But I'm waiting for this PR to land before discussing that one.

Implement "items do not inherit unsafety" note for THIR unsafeck

Implements the "items do not inherit unsafety from separate enclosing items" note from the MIR unsafety checker in the THIR unsafety checker (`-Z thir-unsafeck`) to maintain parity between the two unsafety checkers. The logic to find the separate enclosing item is nearly the same as in the MIR unsafety checker.

rustdoc: use src consistently over source in CSS/JS

The two terms have been used, inconsistently, in closely related spots like the `src/` directory vs `source-files.js`, and with things like `src-sidebar-toggle` vs the `source-sidebar`. This PR changes most use of `source` to `src` instead (except the localStorage configuration variables, which would be very complicated to migrate).

It also renames `.srclink` to `.src`. This is mostly aiming to cut out one of those many little peanut-butter bits of bloat, and is consistent with how other link classes are done (like how you have `a.mod` stylesheet rules, but there's also a `mod` class put on the body tag).
