Rework doc-test attribute documentation example
This PR change the doc-test attribute documentation example to prefer a more neutral example `deny(dead_code)`, instead of `deny(warnings)`, which is less susceptible to breakage across Rust version.

override user defined channel when using precompiled rustc
We need to override `rust.channel` if it's manually specified when using the CI rustc. This is because if the compiler uses a different channel than the one specified in config.toml, tests may fail due to using a different channel than the one used by the compiler during tests.
For more context, see https://github.com/rust-lang/rust/pull/122709#issuecomment-2165246281.
Sync fuchsia test runner with clang test runner
This synchronizes the fuchsia test running code with the clang test runner. This brings with it:
* Improved logging
* Uses the fuchsia image from the SDK version
* Caches the product bundle across test runs
* Strips the binaries to reduce the data sent to the emulator

Replace all `&DiagCtxt` with a `DiagCtxtHandle<'_>` wrapper type
r? `@davidtwco`
This paves the way for tracking more state (e.g. error tainting) in the diagnostic context handle
Basically I will add a field to the `DiagCtxtHandle` that refers back to the `InferCtxt`'s (and others) `Option<ErrorHandled>`, allowing us to immediately taint these contexts when emitting an error and not needing manual tainting anymore (which is easy to forget and we don't do in general anyway)

Rework `feature(precise_capturing)` to represent `use<...>` as a syntactical bound
Reworks `precise_capturing` for a recent lang-team consensus.
Specifically:
> The conclusion of the team is that we'll make use<..> a bound. That is, we'll support impl use<..> + Trait, impl Trait + use<..>, etc.
> For now, we will support at most one such bound in a list of bounds, and semantically we'll only support these bounds in the item bounds of RPIT-like impl Trait opaque types (i.e., in the places discussed in the RFC).
Lang decision in favor of this approach:

All of these tests check if rustc's output contains (or does not) contain certain strings. Does that mean these could be better suited to becoming UI/codegen tests?

Rename `InstanceDef` -> `InstanceKind`
Renames `InstanceDef` to `InstanceKind`. The `Def` here is confusing, and makes it hard to distinguish `Instance` and `InstanceDef`. `InstanceKind` makes this more obvious, since it's really just describing what *kind* of instance we have.
Not sure if this is large enough to warrant a types team MCP -- it's only 53 files. I don't personally think it does, but happy to write one if anyone disagrees. cc ``@rust-lang/types``
