Nyall Dawson aa0d377164 Add separate bool for controlling whether vector layer labels
are enabled

Instead of clearing the labeling configuration in order to
disable labels, we need a way to disable them without
losing the configuration. Labels are oftern temporarily
switched on/off as an analysis tool, and we don't want the
settings to be lost as a result
