Make `TyCtxt::coroutine_layout` take coroutine's kind parameter

For coroutines that come from coroutine-closures (i.e. async closures), we may have two kinds of bodies stored in the coroutine; one that takes the closure's captures by reference, and one that takes the captures by move.

These currently have identical layouts, but if we do any optimization for these layouts that are related to the upvars, then they will diverge -- e.g. https://github.com/rust-lang/rust/pull/120168#discussion_r1536943728.

This PR relaxes the assertion I added in #121122, and instead make the `TyCtxt::coroutine_layout` method take the `coroutine_kind_ty` argument from the coroutine, which will allow us to differentiate these by-move and by-ref bodies.

The codegen crate contains the code to convert from MIR into LLVM IR, and then from LLVM IR into machine code. In general it contains code that runs towards the end of the compilation process.

For more information about how codegen works, see the rustc dev guide.
