Rollup merge of #99435 - CAD97:revert-dollar-dollar-crate, r=Mark-Simulacrum
Revert "Stabilize $$ in Rust 1.63.0" This mechanically reverts commit 9edaa76adce4de737db54194eb13d6c298827b37, the one commit from #95860. https://github.com/rust-lang/rust/issues/99035; the behavior of `$$crate` is potentially unexpected and not ready to be stabilized. https://github.com/rust-lang/rust/pull/99193 attempts to forbid `$$crate` without also destabilizing `$$` more generally. `@rustbot` modify labels +T-compiler +T-lang +P-medium +beta-nominated +relnotes (applying the labels I think are accurate from the issue and alternative partial revert) cc `@Mark-Simulacrum`
