Faster fmt::Display of 128-bit integers, without unsafe pointer
In followup of #135265, hereby the 128-bit part.
* Batches per 16 instead of 19 digits
* Buffer access as array insteaf of unsafe pointer
* Added test coverage for i128 and u128

Improve some attribute docs and rename groups
r? `@nnethercote`
Some naming here got changed at some point, and this feels more consistent. The docs changes were a direct response to `@mejrs` trying to implement a new parsers and running into this.
Fix enter_trace_span!() using wrong $crate paths
This is a followup to rust-lang/rust#140972, where I made a silly mistake and forgot to update `$crate::interpret::tracing_utils::...` to `$crate::interpret::util::...` inside the macro after moving the referenced code from `tracing_utils.rs` to `util.rs`. Sorry about this.

Add tracing import to execution context
In https://github.com/rust-lang/rust/pull/141909, we missed adding the trace_cmd import in the execution context module. This PR fixes that. Additionally, we are updating the mingw-check-2 check command to include BOOTSTRAP_TRACING=1 to help ensure we don't miss such cases in future PRs.

Remove unneeded `check_id` calls as they are already called in `visit_id` in `EarlyContextAndPass` type
Follow-up from [this message](https://github.com/rust-lang/rust/pull/142240/files#r2137474724).
Since `check_id` is already called in `visit_id` which is supposed to be called for each item with an ID, we don't need to manually call `check_id`.

feat: Add `bit_width` for unsigned integer types
- Accepted ACP: rust-lang/libs-team#598
- Tracking issue: rust-lang/rust#142326
This PR adds methods to the primitive unsigned integer types that return the minimum number of bits required to represent an unsigned integer.
Implement `//@ needs-target-std` compiletest directive
Closesrust-lang/rust#141863.
Needed to unblock rust-lang/rust#139244 and rust-lang/rust#141856.
### Summary
This PR implements a `//@ needs-target-std` compiletest directive that gates test execution based on whether the target supports std or not. For some cases, this should be preferred over e.g. some combination of `//@ ignore-none`, `//@ ignore-nvptx` and more[^none-limit].
### Implementation limitation
Unfortunately, since there is currently [no reliable way to determine from metadata whether a given target supports std or not](https://github.com/rust-lang/rust/issues/142296), we have to resort to a hack. Bootstrap currently determines whether or not a target supports std by a naive target tuple substring comparison: a target supports std if its target tuple does *not* contain one of `["-none", "nvptx", "switch"]` substrings. This PR simply pulls that hack out into `build_helpers` to avoid reimplementing the same hack in compiletest, and uses that logic to inform `//@ needs-target-std`.
### Auxiliary changes
This PR additionally changes a few run-make tests to use `//@ needs-target-std` over an inconsistent combination of target-based `ignore`s. This should help with rust-lang/rust#139244.

[^none-limit]: Notably, `target_os = "none"` is **not** a sufficient condition for "target does not support std"
