[WIP] Fix DefaultInitializeRuntimeAttributes

[EZoni]

Overview

Coming soon...

To do

• Particle component names
• Particle user attributes?

[EZoni]

Just with 23f28a3, the following tests failed:

• test_2d_rigid_injection_lab
• test_3d_collider_diagnostics

[EZoni]

Here's what I'm seeing for test_3d_collider_diagnostics with some prints inside DefaultInitializeRuntimeAttributes:

• This branch:

ptile.NAR = 7
ptile.NAI = 0
ptile.NStructReal = 0
ptile.NStructInt = 0
particle_comps.size() = 0
particle_icomps.size() = 0
user_real_attribs.size() = 0
user_int_attribs.size() = 0
ptile.NumRealComps() = 8
ptile.NumIntComps() = 0
ptile.NumRuntimeRealComps() = 1
ptile.NumRuntimeIntComps() = 0

• Main branch:

ptile.NAR = 7
ptile.NAI = 0
ptile.NStructReal = 0
ptile.NStructInt = 0
particle_comps.size() = 8
particle_icomps.size() = 0
user_real_attribs.size() = 0
user_int_attribs.size() = 0
ptile.NumRealComps() = 8
ptile.NumIntComps() = 0
ptile.NumRuntimeRealComps() = 1
ptile.NumRuntimeIntComps() = 0
particle_comps: x
particle_comps: y
particle_comps: z
particle_comps: w
particle_comps: ux
particle_comps: uy
particle_comps: uz
particle_comps: opticalDepthQSR

So what was previously passed as an argument, e.g., via pc.GetRealSoANames(), isn't equivalent to what is set here via ptile.GetStructOfArrays().GetRealNames(), as expected, but the previous implementation seems to be the one returning the correct names for the real components, while the new implementation seems to return an empty vector.

@EZoni Maybe you can do both. If SoA's GetRealNames return non-empty vector, use it, otherwise do it the old way.
