Expand context hint hud element, picking up weapons with use key

[AdamTadeusz]

Description

• Adds contextual hints when the player is hovering over most interactable objects
• Option to highlight the interactable object
• Allows weapon pickup with the use key. The weapon in the corresponding slot (if any) will be automatically dropped (currently even if the new weapon cannot be picked up sometimes)
• On death utility will now drop with one ammo, and a duplicate utility weapon with one ammo will drop for each extra ammo the original weapon had
• Changes how ghost startup sound is played and stopped to work using the ghost with the use key, shows the uplink state hud element if the ghost is not active but sv_neo_ctg_ghost_beacons_when_inactive is enabled, hides uplink hud element after the round is over (when ghost beacons can no longer be drawn)
• Requesting bot to drop a weapon or join squad is now done client side

Toolchain

• Windows MSVC VS2022

CHL2MP_Player::BumpWeapon calls Weapon_Equip and generally i figured we should follow the same logic as in CBasePlayer::GiveNamedItem( after the misyl fix down in CNEO_Player::GiveLoadoutWeapon(
