CMake

• Don't tell JUCE to code sign on mac. These can go away:

...
    HARDENED_RUNTIME_ENABLED TRUE
    HARDENED_RUNTIME_OPTIONS
        "com.apple.security.cs.allow-jit"
        "com.apple.security.cs.disable-library-validation"
        "com.apple.security.device.audio-input"
...

• Unused headers can be deleted.
• DLFCN and internal module experimental code can be moved elsewhere.
• Unused scripts and utils should vanish.
