This error could be better and shouldn't talk about yield. This requires plumbing through extra information about where generators and yields came from so that we can give appropriate diagnostics at later stages of the compiler.

Preserve generator and yield source for error messages

Previously, error messages after HIR lowering all referred
to generators and yield, regardless of whether the original
source was a generator or an async/await body. This change
tracks the kind of each generator and yield source in order
to provide appropriately tailored error messages.

Fixes rust-lang#60615.
