Simulations: Add new simulation data block

This data block will be the container for simulation node trees.
It will be used for the new particle node system (T73324).

The new data block has the type `ID_SIM`.
It is not visible to users and other developers by default yet.
To enable it, activate the cmake option `WITH_NEW_SIMULATION_TYPE`.

New simulation data blocks can be created by running `bpy.data.simulations.new("name")`.
