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.

Add Ceed_Cuda struct to Ceed_Cuda_ref/shared/gen.

Add Ceed_Cuda struct to Ceed_Cuda_ref/shared/gen.

Now Ceed_Cuda_ref/shared/gen act like subclasses and can be properly cast to Ceed_Cuda.

Improved performance of cuda-gen backend (#341)

Thanks-to: Tim Warburton
Some of these optimizations are the results of the knowledge and experience gathered by Tim Warburton and his team in libParanumal and then ported to libCEED.

* Add colocated gradient in 3D.

* Treat the qFunction by slice in 3d to avoid using too many registers.

Optimization of weight kernel and dynamic allocation of shared memory.

- First optimization of weight kernel, kernels are now coalesce but
might not be fully using SMs (need to batch elements per block)
- Switch to dynamic shared memory allocation in order to batch elements
for interpolation and gradient in cuda-shared backend.
- Add GetPreferedMemoryType for cuda-reg and cuda-shared backends.
(Can be removed in the future with delegation of this function)
