Fixes #74800 The definition of `is_x86_feature_detected!` (and similar macros) depends on the platform - it is produced by a `cfg_if!` invocation on x86, and a plain `#[cfg]` on other platforms. Since it is part of the prelude, we will end up importing different hygiene information depending on the platform. This previously required us to avoid printing raw `SyntaxContext` ids in any tests that uses the standard library, since the captured output will be platform-dependent. Previously, we replaced all `SyntaxContext` ids with "#CTXT", and the raw `Span` lo/hi bytes with "LO..HI". This commit adds `#![no_std]` and `extern crate std` to all proc-macro tests that print spans. This suppresses the prelude import, while still using lang items from `std` (which gives us a buildable binary). With this apporach, we will only load hygiene information for things which we explicitly import. This lets us re-add `-Z unpretty=expanded,hygiene`, since its output can now be made stable across all platforms. Additionally, we use `-Z span-debug` in more places, which lets us avoid the "LO..HI" normalization hack.
