Add UI to record a voice message from the composer toolbar

[nimau]

This PR adds the user interface for recording a voice message from the composer toolbar (first part of the story Record and send a voice message)
The recording itself is not yet implemented (but an audio recorder has already been added).

If the feature flag is set, these are the new states of the composer toolbar:

• Default (the composer text field is empty)

• Text present in the composer

• Tap on the voice message button

A tooltip is displayed:

• Longpress on the voice message button

The composer displays the recording view:

• Release the voice message button

The composer displays the voice message preview with the send button:

@nimau I'm missing how to "lock" the recording without the need to keep the recording button pressed all the time. Will it be the "slide up" gesture like in the current Element/IOS?

@jacotec, for this first implementation of voice message recording, it is not currently possible to "lock" the recording.

@nimau Hopefully this will be added? It' pretty useless in the car then, much too dangerous to keep the finger all the time on the phone in the holder. Same for longer messages ...
