Subject: [PATCH] Return kNotImplemented with vst3_no_scale

Ever since 0bed2b7bc04030931f00bb7a2fba06f79cde86f4 REAPER will randomly
not play back one or more audio channels for plugins that support
IPlugViewContentScaleSuport. If you return `kNotImplemented` then this
bug doesn't occur. REAPER should definitely fix this soon. With
`kResultFalse` this issue still occurs, hence this change so you can use
`vst3_no_scale` to work around this REAPER bug.
