First-person: improvements while in noclip state

[MaxLebled]

This fixes noclip looking weird in first-person

• Noclipping now counts as "grounded" so the viewmodel doesn't play falling/airborne anims while flying around.
• Move bob cycle is manually scrubbed at a slow steady rate while noclipping
• On exiting noclip, the bob cycle smoothly winds back down to 0 so there's no pop.
• Positional offset that gets subtly animated while in noclip state, gets removed much faster if aiming down sights
