This leaves only the existence of webview_zygote domain and its
executable's webview_zygote_exec file label as public API. All other
rules are implementation details of this domain's policy and are thus
now private.
Test: Device boots, with Multiproces WebView developer setting
enabled, apps with WebView work fine. No new denials.

Replace the global debuggerd with a per-process debugging helper that
gets exec'ed by the process that crashed.

This removes access to Bluetooth system properties from arbitrary
SELinux domains. Access remains granted to init, bluetooth, and
system_app domains. neverallow rules / CTS enforce that access is not
granted to Zygote and processes spawned from Zygote expcept for
system_app and bluetooth.
The reason is that some of these properties may leak persistent
identifiers not resettable by the user.
Test: Bluetooth pairing and data transfer works

webview_zygote needs to preload the WebView implementation, which may be
an installed APK, so must be able to read and execute code from inside
the APK.
Also add additional neverallow assertions to strengthen some
restrictions on this domain.
Test: WebView apps work after installing a WebView APK.

The webview_zygote is a new unprivileged zygote and has its own sockets for
listening to fork requests. However the webview_zygote does not run as root
(though it does require certain capabilities) and only allows dyntransition to
the isolated_app domain.
