This PR is a about reloading an `Lv2Proc`, e.g. in case of a sample rate change. Prior to this PR, #6419 handled this by first saving the models into XML, then destroying and re-initializing the whole `Lv2Proc` and finally reloading the saved XML. However, #6786 shows that the automation is not properly restored in such a case. This PR thus attempts to not destroy the automatable models, just everything else. This is done by moving `Lv2Proc::createPorts` into the CTOR before calling `Lv2Proc::initPlugin`, which makes `initPlugin()` and `shutdownPlugin()` proper inverses of each other (note that in jalv, the ports are also created before the features are). The new class `Lv2ProcSuspender` adds an RAII interface for reloading the `Lv2Proc`. Note that another, possibly more clean approach would be to separate the features and the plugin from the models ("controls"), to then only destroy the features and the plugin. This could be done by having `Lv2Effect` contain an `Lv2Proc` and `Lv2FxControls` contain an `Lv2ProcControls`. Then the effect classes are the usual way round, and you still maintain the separation between processor and controls in the core LV2 code. (Similarly for the instrument, except we don't have a processor/control split for instruments, so an instance of each class would be contained within the same instrument instance.) - Thanks for this proposal to @DomClark .
