doc: replace recommonmark with MyST and migrate ReST to MyST

This offers more familiar syntax for most writing, as well as natural
$\pi$ math (versus :math:`\pi`) and markdown syntax for all ReST
features.

The API doc stubs remain in ReST as recommended for autodoc.

https://myst-parser.readthedocs.io/en/latest/sphinx/use.html#use-sphinx-ext-autodoc-in-markdown-files

The change was largely implemented using
https://github.com/executablebooks/rst-to-myst/ with some manual
fix-ups. Tables (both ReST built-in tables and list-table) remain under
eval-rst until they can be manually updated.

bugs

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.
