Fix T75210: Frame range does not go down to 0 in the physics tab for mantaflow when clicking the left arrow

Added nore flexibility to cache frame range and ensured validity of frame range.

Fluid: Removed Empty Space option for liquid domains

The option only makes sense for gas domains where there is some density.

Fluid: Optimization for mesh file loading

Improved loading times for mesh files by reading bigger chunks of data from the disk at once.

Fluid: Use dynamic mode whenever active rigid bodies are in the scene

Required for collisions with moving rigid bodies. Otherwise the static optimization mode will be kept and the obstacles would be calculated only once at the beginning.

Fluid: Optimization for liquid / secondary particle file loading

Improved loading times for particles files by reading bigger chunks of data from the disk at once.

Fluid: Removed obstacle levelset optimization

Currently results in unstable particle behavior and incorrect meshing.

Fluid: Small fix for secondary particles

Small tweak to ensure index will not run out of bounds during secondary particle computation.

Fluid: Use different phi for levelset generation

Phi that is used for mesh should be the one that matches particles best.

Fluid: Enforce minimum thickness to planar flow / effector objects

Planar object now have a thickness by default. This should make it more intuitive for users as there is no need to specify an object thickness.

Fix T73988: Mantaflow fluid simulation - Particles for Spray, Foam and Bubbles are one frame ahead of Mesh

Fixes an issue with secondary particles being out of sync with the main simulation. Cleaned up the secondary particle code in general too (making sure that all solver attributes - timestep, framelength, etc. - are set correctly).
