fix #307005: chord playback default not consistent

Resolves: https://musescore.org/en/node/307005

Currently chord symbols playback is off by default
controlled by a global program preference.
This means a given user has to learn the feature exists before using it,
which is not how we handle playback of dynamics, ornaments, etc.
And worse, it means a user might turn it on, hear the chord playback,
save and share a score that relies on it,
but the people he sahres it with (including musescore.com)
will not hear the chords unless they happen to have enabled the option.
And musescore.com won't play it no matter what
(or else, it will always play chords symbols for everyone,
which isn't good either).

This commit removes the preference and enables chord sytmbol playback
according to the style setting and property on the chord symbol itself,
which is exactly how it is done for ornaments etc.
The style setting and property already existed,
they were just being overridden by the program preference.
