First stab at notarization

The distribution will be signed and notarized during an "install" build
and is handled by mac/scripts/build_dist.sh.

The wrapper scripts, mac/Audacity.sh, is no longer needed as it's function
has been integrated into AudacityApp.cpp/main().

Initially, all "hardened entitlements" have been enabled since we don't
know which ones plug-ins will need.

On Mac and Windows, system sleep will be disabled when recording starts
and re-enabled when it ends.
