Doc: improve description of IN and row-constructor comparisons. IN and NOT IN work fine on records and arrays, so just say that they accept "expressions" not "scalar expressions". I think that that phrasing was meant to say that they don't work on set-returning expressions, but that's not the common meaning of "scalar".
Revise the description of row-constructor comparisons to make it perhaps a bit less confusing. (This partially reverts some dubious wording changes made by commit f56651519.) Per gripe from Ilya Nenashev. Back-patch to supported branches. In HEAD and v16, also drop a NOTE about pre-8.2 behavior, which is hopefully no longer of interest to anybody.
