Separate microphone and speaker toggles for handheld radios.

[och-och]

About the PR

Handheld radio (including security radio) have separate actions for toggling microphone and speaker: primary interact for microphone, alt-interact for speaker. Both options also have right-click menu verbs.
Semi-side effect is that intercoms also get toggles in the right-click menu.

Why / Balance

Being forced to broadcast yourself when you just want to listen is not fun, so there should be a way to turn off microphone while receiving.

Technical details

• RadioMicrophoneComponent and RadioSpeakerComponent are now based on a new class - DVRadioToggleable for common fields and polymorphism(?). Both components get GetVerbs events.
• RadioDeviceSystem is predicted by moving most server-side methods to a new _DVA part of SharedRadioDeviceSystem.
• Remove redundant fields from IntercomComponent, use RadioMicrophoneComponent and RadioSpeakerComponent fields instead, as those components are required for intercom to work anyway.
• Replace all handheld-radio-component.ftl localisations.

Test plan

Spawn a couple handhelds, security radio, intercom. Set them to listen and/or broadcast, and say hi 👋.
Examine their examine text correctness, and that verbs correlate to the actions.
