GPU hybridization optimizations
...
This commit includes two optimizations:
- Use CuBLAS for batched linear algebra. Compute Ahat^{-1} Ct using
batched LU with multiple right-hand sides.
- After forming face-to-face connectivity, expose more parallelism
in matrix-matrix kernels.

Deep copy when accessing the DOF map on device
...
Reading reading the DOF map on GPU can cause issues in other parts of the code
when using the debug device. The DOF map is accessed in other places without
explicitly calling HostRead, which fails on non-const access if the device
pointer is valid.

Device execution in HybridizationExtension::ComputeSolution

For now, use ElementDofOrdering::NATIVE. This will need to be changed to
LEXICOGRAPHIC once device assembly of the element matrices is supported.
Also, represent hat DOF types (free interior, free boundary, essential) with
enum instead of raw integer.
