It was possible that var X interface{} = 'x' could cause a compilation failure due to having not calculated rune's width yet. typecheck.go normally calculates the width of things, but it doesn't for implicit conversions to default type. We already compute the width of all of the standard numeric types in universe.go, but we failed to calculate it for the rune alias type. So we could later crash if the code never otherwise explicitly mentioned 'rune'. While here, explicitly compute widths for 'byte' and 'error' for consistency. Fixes #29350.
