Add --voice-note flag for send command (#1973)

Add support for marking audio attachments as voice notes when sending
messages. Voice notes are displayed inline with a play button in Signal
clients, rather than as file attachments.

This addresses a longstanding TODO in AttachmentUtils.java and resolves
the feature request in #1601.

Changes:
- Add 'voiceNote' field to Message record
- Pass voiceNote flag through AttachmentHelper to AttachmentUtils
- Add .withVoiceNote() to SignalServiceAttachmentStream builder
- Add --voice-note CLI argument to SendCommand
- Support voiceNote parameter in JSON-RPC mode

Usage:
  signal-cli send -a audio.m4a --voice-note +1234567890

JSON-RPC:
  {"method":"send","params":{"attachment":"audio.m4a","voiceNote":true,...}}

Closes #1601
