sci-libs/ceres-solver: Bump to 2.0.0

* Based off of sci-libs/ceres-solver-1.14.0.
* Uses existing `USE=openmp` to set new CERES_THREADING_MODEL cmake
  variable.
* Fixes error where `Eigen3Config.cmake` is missing.
* Add `USE=system-mathjax` and associated patch to enable generated doc to
  use local MathJax to render embedded math.

Closes: https://bugs.gentoo.org/806409
