Add `IsTerminal` trait to determine if a descriptor or handle is a terminal
The UNIX implementation uses `isatty`. The Windows implementation uses
the same logic the `atty` crate uses, including the hack needed to
detect msys terminals.
Implement this trait for `Stdin`/`Stdout`/`Stderr`/`File` on all
platforms. On Unix, implement it for `BorrowedFd`/`OwnedFd`. On Windows,
implement it for `BorrowedHandle`/`OwnedHandle`.

Rather than referencing a slice's pointer and then creating a new slice
with a longer length, offset from the base structure pointer instead.
This makes some choices of Rust semantics happier.
The UNIX and WASI implementations use `isatty`. The Windows
implementation uses the same logic the `atty` crate uses, including the
hack needed to detect msys terminals.
Implement this trait for `File` and for `Stdin`/`Stdout`/`Stderr` and
their locked counterparts on all platforms. On UNIX and WASI, implement
it for `BorrowedFd`/`OwnedFd`. On Windows, implement it for
`BorrowedHandle`/`OwnedHandle`.

Fix `Duration::{try_,}from_secs_f{32,64}(-0.0)`
Make `Duration::{try_,}from_secs_f{32,64}(-0.0)` return `Duration::ZERO` (as they did before #90247) instead of erroring/panicking.
I'll update this PR to remove the `#![feature(duration_checked_float)]` if #102271 is merged before this PR.
Tracking issue for `try_from_secs_f{32,64}`: #83400
Queries can provide an arbitrary expression for their description and
their caching behavior. Before, these expressions where stored in a
`rustc_query_description` macro emitted by the `rustc_queries` macro,
and then used in `rustc_query_impl` to fill out the methods for the
`QueryDescription` trait.
Instead, we now emit two new modules from `rustc_queries` containing the
functions with the expressions. `rustc_query_impl` calls these functions
now instead of invoking the macro.
Since we are now defining some of the functions in
`rustc_middle::query`, we now need all the imports for the key types
there as well.
sync thread_local key conditions exactly with what the macro uses
This makes the `cfg` in `mod.rs` syntactically the same as those in `local.rs`.
I don't think this should actually change anything, but seems better to be consistent?
I looked into this due to https://github.com/rust-lang/rust/issues/102549, but this PR would make it *less* likely that `__OsLocalKeyInner` is going to get provided, so this cannot help with that issue.

Detect and reject out-of-range integers in format string literals
Until now out-of-range integers in format string literals were silently ignored. They wrapped around to zero at usize::MAX, producing unexpected results.
When using debug builds of rustc, such integers in format string literals even cause an 'attempt to add with overflow' panic in rustc.
Fix this by producing an error diagnostic for integers in format string literals which do not fit into usize.

Suppress irrefutable let patterns lint for prefixes in match guards
In match guards, irrefutable prefixes might use the bindings created by the match pattern. Ideally, we check for this, but we can do the next best thing and just not lint for irrefutable prefixes in match guards.
Fixes#98361
rustdoc: remove unused CSS `.search-container > *`
The two items it was really intended to target were the buttons, and those both need to have the style set directly on them anyway because the buttons are both child elements of wrappers.

More dupe word typos
I only picked those changes (from the regex search) that I am pretty certain doesn't change meaning and is just a typo fix. Do correct me if any fix is undesirable and I can revert those. Thanks.
Migrate css highlight without change
This is a "previous" version of https://github.com/rust-lang/rust/pull/102663: only migrating to CSS variables, no changes. It's a bit more verbose because rules are not coherent between themes.
