fix: Fixed sound, cones and chocks which depend on LIGHT BEACON (ON)) var

[frankkopp]

Summary of Changes

Wheelchocks and Safety Cones depended on LIGHT BEACON ON
Cabin announcements (Sounds) depended on LIGHT BEACON

LIGHT BEACON == Switch Position
LIGHT BEACON ON == Actual Beacon Light State

This PR fixes this so that:

• Chocks and Cones are gone when the switch is on
  • this avoids the case of an unpowered aircraft on the runway or taxiway having them visible
• Cabin announcements only play when beacon lights are actually on

Discord username (if different from GitHub): Cdr_Maverick#6475

Testing instructions

• Test chocks & cones visibility in powered an unpowered states depending on switch
• Test announcements playing only when aircraft is powered and switch is on.
