Strided Restrictions

make style

CUDA - remove extra variable declaration in cuda/gen

CUDA - cuda/reg recompute blocksize

CUDA - cuda/gen fixes

CUDA - fix readSliceQuadsStrided signature

CUDA - fix writeDofsStrided3d signature

Interface - update constants to be const...ant

ElemRestriction - make strides const

Co-Authored-By: Jed Brown <jed@jedbrown.org>

Style - fix style error

CUDA - use strides as template parameters for cuda/gen

Python - add CEED_ELEMRESTRICTION_NONE

ElemRestriction - add CEED_ELEMRESTRICTION_NONE so we can stop making dummy restrictions for CEED_EVAL_WEIGHT fields

Make style

CUDA - initial impl of strided restrictions in cuda/gen

CUDA - fix indices and strides arguments in cuda/gen

CUDA - update ref/reg restrictions to use CEED_STRIDES_BACKEND {1, nelem*elemsize, elemsize}

magma backend: replace vector alias with explicit backend strides

Restriction - add CEED_STRIDES_BACKEND

CPU - fix CPU backend stridiniding for CEED_BACKENDSTRIDE

magma backend: add optimization for CEED_STRIDES_BACKEND in restriction

Restriction - add CEED_STRIDES_BACKEND
