[CoC/Anomaly] Optional grenade launcher switch animation usage.

[Neloreck]

Just changing how animation is handled for grenade launcher toggling.

In case of missing animation just toggle switch. It is normal for some weapons with GL where switching mode does not require adjusting weapon / placing hand on another position. Found this one when was playing with integration of anomaly weapons and noticed some missing anm_switch_g anm_switch animation fields.

Main question as for now is logging -> probably prettier variant without method overloading can be implemented?

Changes

• Just changing how animation is handled for grenade launcher toggling, allow cases without animation
• Still respect variant with two animations (SoC support?) and add comment for it
• Add param to prevent not_found log messages when doing animation checks / playing SoC animation variant (currently it produces 2 messages if animation is not found, I believe it is always 1 message for SoC)
