Support " echoCanceller: software"

Webrtc should be enabled with echoCanceller: software in the dring.yml

For now "echoCanceller: system" is only used in pulselayer to do bool ec = preference_.getEchoCanceller() == "system";

added media enhancement labels

mentioned in issue #741 (closed)

with https://review.jami.net/c/jami-daemon/+/21976, the following options are valid for the YAML option "echoCancel" in dring.yml:

• "auto": try to use system echo canceller if it exists, otherwise fall back to the chosen audio processor's echo canceller
• "audioProcessor": only use chosen audio processor's echo canceller
• "system": only use system's echo canceller
• "null" or any other string: don't use any

an audio processor is chosen via the "audioProcessor" YAML option:

• "webrtc": WebRTC Audio Processing
• "speex": Speex DSP
• "null" or anything else

@thildebrandt I guess jami-docs should be updated (I think in the FAQ it will be a good place)
