This is a reland of bbbf1a7f50
Original change's description:
> Redesign program key construction
>
> This does two things:
> 1) Moves responsibility for bit-packing portions of the key into the key
> itself. A new GrKeyBuilder type manages adding bits, with asserts to
> ensure a value always fits in the requested number. In theory this
> will let us generate smaller keys overall, at the expense of slightly
> more complex code during construction.
> 2) Adds a string label parameter for key methods that fold in data. For
> new methods, the label is required. To ease migration, the old add32
> does not require a label (yet). This will let us generate detailed,
> human readable keys, either based on SK_DEBUG, or a runtime option
> (if we're comfortable paying the cost).
