Changed BlockOperator and BlockDiagonalPreconditioner to copy data to and from separate vectors for each block multiplication, in order to work on device. Updated MINRES for device runs. Now ex5 works on device.

Introduce a new Memory class for handling host + device allocations
...
and transfers.
The Memory class is now used by some MFEM classes (like Array and
Vector) which can be used on the Device. Such classes now provide
methods to access the underlying Memory object, e.g. GetMemory.
Updated ex1/ex1p and ex6/ex6p to not need to enable/disable the
Device at specific points -- the Device is now enabled just at the
start. Also, the same examples can now run on Device (e.g. -d cuda)
without the partial assembly option (-pa) -- full assembly will
be still done on CPU but the sparse matrix action and vector
operations will be done using the Device.
Reverted changes in class DenseMatrix related to using the Device.
At this point, DenseMatrix operations are only used for small matrices
and using the Device in this case is not a good option.

Updating to remove redundant row/column block counts and offset arrays. Also updated documentation to reflect difference between diagonal and off-diagonal blocks in the preconditioner.
...
Not done (because I'm waiting for confirmation on it) is adding a check in SetBlock to ensure we only fill the lower triangular.
