Correct annotations for WebViewUpdateService/Manager.
WebViewUpdateManager.getInstance() was only able to return null if
called on a device without FEATURE_WEBVIEW, which should not be
happening in the first place per the @RequiresFeature annotation. It
already WTFed if called from a system process rather than returning
null; make it throw UnsupportedOperationException for non-system
processes so that it can be @NonNull.
WebViewUpdateService.getValidWebViewPackages() should be documented as
requiring INTERACT_ACROSS_USERS permission. The underlying API has
always relied on this permission so there is no behavioral change here.
Remove the QUERY_ALL_PACKAGES permission from getValidWebViewPackages as
it's not enforced; the normal package visibility rules are applied to
the result. Note in the javadoc that callers should have
QUERY_ALL_PACKAGES to get a complete list.
