Single Source QFunction (#304)

Introduce a new macro CEED_QFUNCTION that allows to define qFunctions in a single source code independently of the targeted backend.

Thanks-to: Jeremy Thompson
Thanks-to: Jed Brown
This work is the result of a fruitful discussion between Jed Brown, Jeremy Thompson and Yohann Dudouit. Jeremy Thompson also implemented important features in this commit and was very active and helpful all along the progress of this work.

[NEWS] Breaking change: QFunctionField parameter 'ncomp' changed to 'size'. This change requires setting the previous value of 'ncomp' to 'ncomp*dim' when adding a QFunctionField with eval mode 'CEED_EVAL_GRAD'.

* First steps toward cuda-gen backend!

* Closer to real code generation.

* Generated code should be ready for nvrtc.

* The code generation skeleton is ready.

* Hack with the qfunction to make the operator kernel compile.

* Some tweaks in the makefile + Input fields structure change.

* Remove using cout.

* 1d interp and grad device functions.

* 1d readDofs, readQuads, writeDofs, writeQuads.

* Remove dead code.

* - weight functions for 1d,2d,3d
- link the indices to the kernel
- link the fields to the kernel
- link the basis to the kernel

* Add the qFunction reader + inlining

* Add qf files for the tests.

* Add qf file for ceed/ex1

* Add qf file for mfem/bp1

* All tests pass.

* Add qFunction for mfem/bp3, petsc/bp1, and petsc/bp3.

* mfem/bp1 passes + remove dead code

* Fix a bug in n_quads_out for writeQuads

* mfem/bp3 passes.

* All tests all examples pass.

* Temporary tweaks for mfem benchmarking

* Add Context management.

* Modify .qf files to take into account the context.
