Add @SinceKotlin and KDoc for ContextFunctionTypeParams

Initially, it was added accidentally as part of e3f987459c
and missed all out processes.

Adding @SinceKotlin("1.7") after the annotation has already been
published before is not really a problem, because it only may be used
with an experimental `-Xcontext-receivers` flag, thus it doesn't have
to be a part of our regular backward compatibility routine.
