Generate templated builder setters for fields taking an objecttype

We already do this for hand-written extension functions but can now also
implement it for setters since `vk_parse` fields are available within
the builder generator code: when a field refers to another field for
setting its `objecttype`, that `VkObjectType` field setter is omitted
and instead assigned when the object is set, based on a type generic
that implements the `Handle` trait instead of an untyped `u64`.
