pw_kernel: Signal objects with masked SignalUpdate

Every ObjectBase::signal() caller passed a closure that was a pure mask
operation, so each call site paid for its own instantiation of the
update path. Take a SignalUpdate (mask and values) instead.

Code size (bytes):

  mps2_an505         ipc.elf         66348 -> 65768  (-580)
  mps2_an505         wait_group.elf  68388 -> 67848  (-540)
