anv: Remove special allocation for anv_push_constants
The key reason for that mechanism is gone: all the extra optional data
that could be in the anv_push_constants was moved elsewhere. At this
point, just put anv_push_constants directly in anv_cmd_state (part of
anv_cmd_buffer).
v2: Remove a NULL check we don't need anymore in
anv_cmd_buffer_push_constants(). (Lionel)
Fix size we consider for valid push params. (Lionel)
