Subject: Fluid: Initial support for 2D fluid simulations

Initial adjustments for 2D (real-time) simulations.

Basic functionality includes:
- 2D/3D switcher in domain settings
- 2D simulation support for smoke/fire, wavelet noise, liquid
particles, secondary particles
- UI switcher to choose the axis that will be simulated on
- Planar visualization in workbench render

Some things that remain to do (non-exhaustive list):
- Eevee & Cycles support
- Liquid meshing
- Liquid viscosity solver
