Core/Entities: Fix some weird movement due to los issues (#21125)

* Core/Entities: Fix some weird movement due to los issues
- Made LoS check use collisionHeight instead of midsection. Value was too low.
- Gnomes will now have a breath bar more quickly than for example a tauren.
- Changes have been made to checking for ground z as well, some tweeking might be needed but removed most of the scattered +2.0f/+0.5f/we
* Add 0.05f to isInAir check in Creature::UpdateMovementFlags
