Jon Ross-Perkins 917ce5bd6b Fix a duplicate diagnostic on incomplete return types. (#6684) ...

For example, see toolchain/check/testdata/class/fail_incomplete.carbon
for the diagnostic changes. `IncompleteTypeInFunctionReturnType` should
remain, while the redundant `IncompleteTypeInFunctionParam` is removed.

Note I'm deliberately trying to validate the return type after other
parameters, because I think that's the better user experience. This does
also incrementally change IR.
