This schema is helpful for people writing custom target spec JSON. It
can provide autocomplete in the editor, and also serves as documentation
when there are documentation comments on the structs, as `schemars` will
put them in the schema.

This test depends on the target-specific behavior of crt-static for musl
targets. However, running the testsuite on a musl host requires
setting `crt-static` to `false`, as it wouldn't otherwise be possible to
build rustc. This in turn will enable `-Ctarget-feature=-crt-static` for
all tests, mismatching the expected `+crt-static` for the musl target
tested in this testcase.
Since this test specifically tests the default value of `crt-static` for
the musl target, ignoring it entirely makes more sense than manually
setting `-Ctarget-feature=+crt-static` here, but both would be valid
approaches.

In a PR to emit warnings on misuse of `--print native-static-libs`,
we did not consider the matter of composing parts of build systems.
If you are not directly invoking rustc, it can be difficult to know
when you will in fact compile a staticlib, so making sure everyone
uses `--print native-static-lib` correctly can be just a nuisance.
This reverts the following commits:
- f66787a08d57dc1296619b314d2be596085bfeef
- 72a9219e82c157041bfc8dfd378c9cb2b09c0650
- 98bb597c05c32365abbd6898f278b097352774ed
- c59b70841c36277464b51161e3fcf12dfcb667e0
Next cycle we can reland a slightly more narrowly focused variant or one
that focuses on `--emit` instead of `--print native-static-libs`.
But in its current state, I am not sure the warning is very useful.

Can be fixed properly later by adding a new flag for non-exhaustive line annotation checking

Add unstable `--print=crate-root-lint-levels`
This PR implements `--print=crate-root-lint-levels` from MCP 833 https://github.com/rust-lang/compiler-team/issues/833.

- Document test intent to check for `-Whelp` suggestion if
`--print=lints` was specified.
- Move this test under `tests/ui/print-request/` and rename it to
`print-lints-help.rs` to better reflect what it is checking.

As an unstable print request.

I can't find any dedicated tests that actually exercises the stability
gating (via `-Z unstable-options`) of print requests, so here's a
dedicated one.
I coalesced `tests/ui/feature-gates/feature-gate-print-check-cfg.rs`
into this test, because AFAICT that print request is not feature gated,
but only `-Z unstable-options`-gated just like other unstable print
requests.

The deployment target environment variable is OS-specific, and if you're
in a place where you're asking `rustc` for the deployment target, you're
likely to also wanna know the environment variable.

People often parse `-vV` output to get to the host triple, which is
annoying to do. It's easier to just get it directly.
