Subject: [PATCH] LVSL: track samplerate/tempo changes in VstPlugin base class

Up to now changes of samplerate or tempo only have been tracked by the
VeSTige plugin while e.g. the VstEffect didn't forward such changes to the
RemotePlugin. Moving according code from VeSTige to VstPlugin base class
fixes this issue.
(cherry picked from commit 5dd68ea7f33d2cd7fcba50ad4b8cb26fb4566c14)
