Reserve more space for built-in types in id space.

We are running out of type ids for built-in types, 255 is not enough.
QMetaType already contains about ~70 types, situation is maybe not
tragic now, but there is a great chance that we will want to add more
built-in types from different modules like jsondb or declarative. Then
it might be tight, because we are not allowed to reorganize type ids
(it would be a binary incompatible change).

This change was not possible up to now. Old moc generated code assumes
that type id can be safely stored in 8 bits.

This is source compatible change.
