runtime: add partial lock order between mspanSpecial and gcBitsArenas 

CL 493275 started using gcBits for pinner bits. This means gcBits can be
allocated while holding the mspanSpecial lock. This is safe because
these were just parallel in the partial order, but now they need an
explicit edge between them.

For #58277.
