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")`. Reviewers: brecht Differential Revision: https://developer.blender.org/D7225

Code Style: use "#pragma once" in source directory This replaces header include guards with `#pragma once`. A couple of include guards are not removed yet (e.g. `__RNA_TYPES_H__`), because they are used in other places. This patch has been generated by P1561 followed by `make format`.

Simulation: Add modifier to access simulation data For now the "Simulation" modifier only exists for point cloud objects, because we need this for the particle system. Right now, the modifier is doing nothing. There is a new `DEG_add_simulation_relation` function that is used by the modifier to make sure that the simulation is evaluated before the modifier is executed.

Particles: give emitter its own state High quality emitters need to maintain state themselves. For example, this it needs to remember when it spawned the last particle. This is especially important when the birth rate is changing over time. Otherwise, there will be very visible artifacts. It is quite likely that other components of the simulation need their own state as well. Therefore, I refactored the `SimulationState` type a bit, to make it more extensible. Instead of using hardcoded type numbers, a string is used to identify the state type. Also, instead of having switch statements in many places, there is a new `SimulationStateType` that encapsulates information about how a specific state is created/freed/copied/... I removed the integration with the point cache for now, because it was not used anyway in it's current state.
