Rename modules

[atsushieno]

I have no idea why, but those juceaap modules have flipped module names. I thought I fixed them once, but apparently not.

To avoid confusion, we would rename those modules to the following:

• juceaap_audio_processors => aap_audio_plugin_client
• juceaap_audio_plugin_client => aap_audio_processors

This will involve a lot of changes everywhere in aap-juce-xxx repos.
