Fix a MatSetRandom bug with unassembled MATMPIAIJ

When doing MatSetRandom on a preallocated but unassembled matrix X, we can not
simply calling MatSetRandom on X's B. Since B is not assembled, it has a column
size as wide as X. Calling MatSetRandom(B,r) might generate nonzeros belonging
to X's A.

Based on discussion with Oana I am adding a MatPinToCPU() and VecPinToGPU() capability. For matrices this
will prevent copies to the GPU when they will never be used there. For vectors this will
prevent vectors from boucing back and forth between the CPU and GPU when most of the work is in the CPU. An
example of the place that needs to avoid bouncing is in MatFDColoringApply_XXXX()
