musicbrainz: remove trm element which is not useful any more

Browse source 
TRM IDs are MusicBrainz' old audio fingerprinting system from
Relatable, they were phased out in favour of MusicIPs PUIDs.

/**
* SECTION:element-trm
*
* GstTRM computes <ulink url="http://www.musicbrainz.org/">MusicBrainz</ulink>
* TRM identifiers for audio streams using libmusicbrainz.
*
* A TRM identifier is something like an 'acoustic fingerprint', the aim is
* to uniquely identify the same song regardless of which source it comes from
* or which audio format the stream is in.
*
* The TRM element will collect about 30 seconds of audio and let
* libmusicbrainz calculate a preliminary audio signature from that. That audio
* signature will then be sent over the internet to a musicbrainz.org server
* which will calculate the TRM for that signature.
*
* The TRM element will post a tag message with a #GST_TAG_MUSICBRAINZ_TRMID
* tag on the bus once the TRM has been calculated (and also send a tag event
* with that information downstream).
*
* <refsect2>
* <title>Example pipeline</title>
* |[
* gst-launch -m filesrc location=somefile.ogg ! decodebin ! audioconvert ! trm ! fakesink
* ]| calculate the TRM and print the tag message with the TRM ID.
