A small program to turn on or off accessibility support by making calls to fuchsia::accessibility::Toggler. Run this program with:
run a11y_toggler [true/false]
Requires an a11y_manager process that implements fuchsia::accessibility::Toggler service to be available to connect. The current method for starting a11y_manager should be dynamically by sysmgr when a client tries to connect to one of a11y_manager's FIDL interfaces. This is done by listing the interfaces a11y_manager implement in garnet/bin/sysmgr/config/services.config.
