CPUParticles2D damping is limited to 100

Issue description

In the editor, the value for CPUParticles2D.damping is arbitrarily clamped to 100.0:

This can be hacked around by creating a damping curve that moves from zero immediately to the actual value you want (eg, 250):

It may also be hackable by setting the value in code (I haven't confirmed this).

Steps to reproduce

• Create a CPUParticles2D node
• Give it some high velocity that you want to dampen quickly (say, 1000)
• Try to dampen it to 300
• See that you can't raise the value above 100

This can be solved by adding ,or_greater in the property hint to keep 100 as max for the slider but still allow manual input to go above. This was done for (GPU) ParticlesMaterial but not CPUParticles and CPUParticles2D:

scene/3d/cpu_particles.cpp
1479:   ADD_PROPERTYI(PropertyInfo(Variant::REAL, "damping", PROPERTY_HINT_RANGE, "0,100,0.01"), "set_param", "get_param", PARAM_DAMPING);

scene/2d/cpu_particles_2d.cpp
1339:   ADD_PROPERTYI(PropertyInfo(Variant::REAL, "damping", PROPERTY_HINT_RANGE, "0,100,0.01"), "set_param", "get_param", PARAM_DAMPING);

scene/resources/particles_material.cpp
55:     shader_names->damping = "damping";
1302:   ADD_PROPERTYI(PropertyInfo(Variant::REAL, "damping", PROPERTY_HINT_RANGE, "0,100,0.01,or_greater"), "set_param", "get_param", PARAM_DAMPING);

It can be relevant to check if other parameters of ParticlesMaterial have ,or_greater without it being present in the equivalent of CPUParticles*.

I'll give it a try.

Ah, we still need this for master

Hi, There seem to be one damping_min and one damping_max parameter, which one should be marked as "or_greater", I guess the damping_max?
