Prefer avdmanager from cmdline-tools

The Android SDK tools are deprecated in favor of the command line tools.
Trying to use avdmanager from the deprecated tools fails on OpenJDK 11
with since it can't find the `javax/xml/bind/annotation/XmlSchema`
class. Try `cmdline-tools/latest/bin/avdmanager` first.
