Install install backend headers under include/ceed/

This makes it possible to distribute source plugins that provide
additional backends. It's also used in MFEM, perhaps temporarily.

Deprecate ceed-backend.h, which was not previously installed, but some
users accessed it from an in-place build.

Also install CUDA and HIP headers that allow users to provide CUfunction
and hipFunction_t.

Full assembly of CeedOperator (#712)

* Add CeedOperatorLinearFullAssemble() to explicitly assemble a CeedOperator

The output format is a stream of (row, column, value) triples, which client
code can use to assemble a sparse matrix by adding the values in the
appropriate places.

* Add full assembly test for triangular mesh, t563-operator.c, which is analogous to t536-operator.c

* assembly: change interface to separate nonzero structure from values

* assembly: add potential backends for CeedOperatorLinearAssemble, CeedOperatorLinearAssemblySymbolic

* assembly: use CeedMatrixMultiply() instead of hand-rolled duplicated code

This also involves switching some arrays from column-major ordering to
row-major ordering.

* Remove CeedMatrixMultiply from ceed-impl.h because it is already in ceed-backend.h

* assembly: modify use of fallback resource

* operator - use new error codes in full assembly

* style - minor

* operator - switch default fallback to none

* operator - fix fallback for full assembly

* operator - fix fallback usage

* operator - fix fallback for digonal assembly

* avx - revert bug
