Avoid setup ANGLE again when determine whether to show toast.

Previously after the application is launched, the GraphicsEnvironment
will call into setup ANGLE again to check whether the in use toast
message dialog should be shown. However, this step is unnecessary and
creates some overhead. This patch eliminates the call into ANGLE setup
and only check whether ANGLE is used.

Bug: b/283858001
Test: check toast message when opt-in and opt-out
