Add ParticleOptions.SCALE back to the API

[Wolfizen]

This particle type was commented out, I implemented this option in SpongePowered/Sponge#3368 so this PR adds the option back to the API.

I've changed this documentation because dust is the only particle whose size can be changed with the /particle command (MC 1.16). I'm not sure if there are other particles that can still have their size modified by packet options.

@Wolfizen This looks good.

Can you add a default method to ParticleEffect.Builder ? See

SpongeAPI/src/main/java/org/spongepowered/api/effect/particle/ParticleEffect.java

Lines 160 to 194 in 32cad1a

@ImMorpheus Done and re-tested. :)
