extmod/moductypes: Validate the descriptor tuple.
Fixes various null dereferencing, out-of-bounds memory accesses and
`assert(0)` failures in the case of an invalid `uctypes` descriptor.
By design `uctypes` can crash because it accesses arbitrary memory, but at
least describing the descriptor layout should be forced to be correct and
not crash.
Fixes issue #12702.
