juce_audio_processors: Exclusively use JUCE_INTERNAL_HAS_* macros in place of JUCE_PLUGINHOST_* macros

This change also moves the PLUGINHOST config flags to the
juce_audio_processors_headless module header, as this is now the
lowest-level module that uses these flags. This change shouldn't require
any Projucer/CMake changes.
