This removes the support to emit runtime calls in Liftoff code and uses
WebAssembly runtime stubs instead. Calls to such stubs are smaller and
more efficient. They also use embedded builtins directly instead of the
on-heap {Code} object trampolines. This also removes the last use of a
runtime call that passes a dynamically loaded CEntry builtin from the
macro assembler.
