go/types, types2: reorder channel sends to extract value target type

For channel sends, we currently check the sent value before inspecting
the channel element type. If we check the channel element type first,
we can extract a target type for the value. This change reorders
processing to do so.

This is a necessary prerequisite for composite literal type inference.

For #12854
