Update biparabolic Euler case and add to serial regression tests

- Replace deprecated EXT_ITER with ITER
- Fix swapped CFL_ADAPT_PARAM values (factor-down must be < 1.0)
- Switch from JST to ROE with MUSCL and Venkatakrishnan limiter for
  better robustness at Mach 1.7
- Remove unused adjoint, design-variable, and equivalent-area settings
- Disable multigrid and add case to serial_regression.py
