compiletest: use target cfg instead of hard-coded tables
This changes compiletest to use `rustc --print=cfg` to dynamically determine the properties of a target when matching `ignore` and `only` rules instead of using hard-coded tables or target-triple parsing (which don't always follow the `<arch><sub>-<vendor>-<sys>-<abi>` pattern). The benefit here is that it will more accurately match the target properties, and not require maintaining these extra tables.
This also adds matching the `target_family` in ignore rules. The primary benefit here is so that `ignore-wasm` works as expected (matching all wasm-like targets). There were already several tests that had `ignore-wasm` in them (which previously had no effect), so it is evident that some people expected that to work. This also adds `ignore-unix/only-unix`.
There is some risk that this changes the behavior from before since the tables aren't quite the same as the target properties. However, I did fairly extensive comparisons to see what would be different. https://gist.github.com/ehuss/5bf7ab347605160cefb6f84ba5ea5f6b contains a full list of differences for all targets for all tests. I do not think any of the affected target/test combinations are things that are actually tested in CI. I tested several of the more unusual test images (test-various, dist-various-1, wasm32), and they seem fine.
A summary of most of the reasons behind the differences:
- wasm64-unknown-unknown wasm32-wasi now match "wasm"

Improve crate selection on rustdoc search results page
Resolves all of issue #93240
Reproduces a similar change as #99086, but with improvements
In particular, this PR inlcludes:
* redesigning the crate-search selector so the background color matches its surroundings
* decrease the font of the dropdown menu to a reaonable size
* add a hover effect
* make the color of the arrow theme-dependent, using a surrounding div, with :after pseudo-element
that can then be transformed using CSS filters to approximate the desired color
* fix the text "in" to match the title font
* remove the "for xyz" in the "Results for xyz in [All crates]" title when
searching for search term "xyz"; you can already see what you're searching for
as it's typed in the search bar!
* in line with #99086, handle super-long crate names appropriately without a long <select>
element escaping the screen area; the improvement is that we also keep the title
within a single line now; uses some flex layout shenanigans...
* the margins / paddings are adjusted so the selected label of the <select> fits within
the rest of that title nicely; also some inconsistency in the way that Firefox renders
a <select> with "appearance: none" (roughly 4px more padding left and right of the text
than e.g. Chrome) is worked around, and it now produces a result that looks (essentially)
identical to Chrome
* the color of the help menu and settings menu border in light theme is made to match with
the color of the corresponding buttons, like they do (match) in the ayu theme
* the casing of "All crates" changes to "all crates"
* the new tests from #99086 are temporarily disabled, until they can be adapted later

errors: don't fail on broken primary translations
If a primary bundle doesn't contain a message then the fallback bundle
is used. However, if the primary bundle's message is broken (e.g. it
refers to a interpolated variable that the compiler isn't providing)
then this would just result in a compiler panic. While there aren't any
primary bundles right now, this is the type of issue that could come up
once translation is further along.

Error on broken pipe but do not backtrace or ICE
Windows will report a broken pipe as a normal error which in turn `println!` will panic on. Currently this causes rustc to produce a backtrace and ICE. However, this is not a bug with rustc so a backtrace is overly verbose and ultimately unhelpful to the user.
Kind of fixes #98700. Although this is admittedly a bit of a hack because at panic time all we have is a string to inspect. On zulip it was suggested that libstd might someday provide a way to indicate a soft panic but that day isn't today.

Generally most predicates should only deal with well formed inputs, e.g. a `&'a &'b (): Trait` predicate should be able to assume that `'b: 'a` holds. Normalization can loosen wf requirements (see #91068) and must therefore not be used in places which still have to check well formedness.

Don't ICE while suggesting updating item path.
When an item isn't found, we may suggest an appropriate import to `use`. Along with that, we also suggest updating the path to work with the `use`. Unfortunately, if the code in question originates from a macro, the span used to indicate which part of the path needs updating may not be suitable and cause an ICE (*). Since, such code is not adjustable directly by the user without modifying the macro, just skip the suggestion in such cases.
(*) The ICE happens because the emitter want to indicate to the user what code to delete by referencing a certain span. But in this case, said span has `lo == hi == 0` which means it thinks it's a dummy span. Adding a space before the proc macro attribute is enough to stop it from ICE'ing but even then the suggestion doesn't really make any sense:
```
help: if you import `DataStore`, refer to it directly

`#[rustc_default_body_unstable]` controls the stability of default bodies in traits.
For example:
```rust
pub trait Trait {

fn item() {}
}

In order to implement `Trait` user needs to either
- implement `item` (even though it has a default implementation)
- enable `#![feature(feat)]`
This is useful in conjunction with [`#[rustc_must_implement_one_of]`](https://github.com/rust-lang/rust/pull/92164), we may want to relax requirements for a trait, for example allowing implementing either of `PartialEq::{eq, ne}`, but do so in a safe way — making implementation of only `PartialEq::ne` unstable.

Add option to `mir::MutVisitor` to not invalidate CFG.
This also applies that option to some uses of the visitor. I had considered a design more similar to #100087 in which we detect if the CFG needs to be invalidated, but that is more difficult with the visitor API and so I decided against it. Another alternative to this design is to offer an API for "saving" and "restoring" CFG caches across arbitrary code. Such an API is more general, and so we may eventually want it anyway, but it seems overkill for this use case.
