Fix T88715: particle size influence texture not working for 'keyed' or 'none' physics types

This was reported for the special case of mapping with "Strand /
Particle" coords, but was not working with other coordinates either.

Dont see a reason for not supporting Size influence textures for these
kinds of particles (and since these types of particles have an "age"
like all others as well, even the "Strand / Particle" coords are
supported here as well)
