VST3: Fix error when building VST3 plugins

Browse source 
On macOS 10.15, stdatomic.h (included by the VST3 SDK) defines a macro
named atomic_thread_fence when building in C++20 mode. This macro was
trampling over a call to std::atomic_thread_fence from the C++ atomic
header, made in juce_Atomic.h.

No JUCE implementation files use the C11 atomic functions, so I think
it's safe to just undef the problematic symbol after including all the
VST3 implementation files.
