VST3 Client: Add support for IParameterFinder interface

Browse source 
This allows hosts such as Cubase and MultitrackStudio to locate
parameters based on the current mouse position.

Users must override and implement getControlParameterIndex in order for
the parameter to be reported to the host.

The DSPModulePluginDemo shows one possible strategy for implementing
this function.

@ -94,7 +94,12 @@ public:
If the given component represents a particular plugin parameter, then this
method should return the index of that parameter. If not, it should return -1.
Currently only AAX plugins will call this, and implementing it is optional.
If not overridden, this will return -1 for all components.
This function will be called by the host in AAX and VST3 plug-ins in order to map
screen locations to parameters. For example, in Steinberg hosts, this enables the
"AI Knob" functionality, which enables hardware to control the parameter currently
under the mouse.
