This is bad function name. Actually set of supported rounding modes depends on
the used target. For example not every target supports rounding
`NearestTiesToAway`. But any rounding mode must fit 3 bits. So the function is
about loose validation.
If metadata will be used fo "fpe.round", this function would be unnecessary.
