go/types: factor out usage of implicit type

There was some duplication of logic interpreting the implicit type of
an operand in assignableTo and convertUntyped. Factor out this logic to
a new 'implicitType' function, which returns the implicit type of an
untyped operand when used in a context where a target type is expected.
I believe this resolves some comments about code duplication. There is
other similar code in assignable, assignableTo, and convertUntypes, but
I found it to to be sufficiently semantically distinct to not warrant
factoring out.
