[w3c/permissions] Permission query algorithm should be able to fail (#135)

The [permission query algorithm](https://w3c.github.io/permissions/#permission-query-algorithm) doesn't currently accommodate features that need to validate their descriptors, which can cause the query to fail. Like with the [request algorithm](https://w3c.github.io/permissions/#permission-request-algorithm), we should allow the customized query algorithm to throw.
