v3d: rebind sampler view if resource changed the BO

v3d: rebind sampler view if resource changed the BO

When discarding the whole resource to create a new one, if this resource
is used by a sampler view, a rebind must be done to use the new
resource.

But this must be done when setting the sampler views, because we don't
have access to those samplers before.

v2:
 - Pack shader state on setting sampler views (Iago)
 - Use a serial ID to know when to rebind sampler views (Juan)

v3:
 - Move check to caller (Iago)
 - Keep rebind sampler view on BO change (Iago)

v4:
 - Rename "serial_bo" to "serial_id" (Iago)
 - Add comments (Iago)
