Rollup merge of #137489 - RalfJung:no-more-rustc_intrinsic_must_be_overridden, r=oli-obk

Browse source 
remove `#[rustc_intrinsic_must_be_overridde]`

In https://github.com/rust-lang/rust/pull/135031, we gained support for just leaving away the body. Now that the bootstrap compiler got bumped, stop using the old style and remove support for it.

r? `@oli-obk`

There are a few more mentions of this attribute in RA code that I didn't touch; Cc `@rust-lang/rust-analyzer`
