Auto merge of #95960 - jhpratt:remove-rustc_deprecated, r=compiler-errors

Browse source 
Remove `#[rustc_deprecated]`

This removes `#[rustc_deprecated]` and introduces diagnostics to help users to the right direction (that being `#[deprecated]`). All uses of `#[rustc_deprecated]` have been converted. CI is expected to fail initially; this requires #95958, which includes converting `stdarch`.

I plan on following up in a short while (maybe a bootstrap cycle?) removing the diagnostics, as they're only intended to be short-term.
