make unsupported_calling_conventions a hard error

This has been a future-compat lint (not shown in dependencies) since Rust 1.55, released 3 years ago. Hopefully that was enough time so this can be made a hard error now. Given that long timeframe, I think it's justified to skip the "show in dependencies" stage. There were [not many crates hitting this](https://github.com/rust-lang/rust/pull/86231#issuecomment-866300943) even when the lint was originally added.

This should get cratered, and I assume then it needs a t-compiler FCP. (t-compiler because this looks entirely like an implementation oversight -- for the vast majority of ABIs, we already have a hard error, but some were initially missed, and we are finally fixing that.)

Fixes https://github.com/rust-lang/rust/pull/87678

/// The `unsupported_calling_conventions` lint is output whenever there is a use of the
/// `stdcall`, `fastcall`, `thiscall`, `vectorcall` calling conventions (or their unwind
/// variants) on targets that cannot meaningfully be supported for the requested target.
///
/// For example `stdcall` does not make much sense for a x86_64 or, more apparently, powerpc
/// code, because this calling convention was never specified for those targets.
///
/// Historically MSVC toolchains have fallen back to the regular C calling convention for
/// targets other than x86, but Rust doesn't really see a similar need to introduce a similar
/// hack across many more targets.

/// ### Example
///
/// ```rust,ignore (needs specific targets)
/// extern "stdcall" fn stdcall() {}
/// ```
///
/// This will produce:
///
/// ```text
