Bug 1976779 - rsclientcerts: make each backend responsible for rate-limiting calls to find_objects r=jschanck Before this patch, `rsclientcerts::manager` would rate-limit calls to `find_objects` to once every 3 seconds because the underlying operation can be time-consuming (in particular, on macOS and Windows, if there are many certificates/keys available). On Android, keys aren't available until the user selects one, which means that if a call to `find_objects` happened before the selection prompt was shown (which is what happens) and the user chose one in less than 3 seconds, the backend wouldn't search again, thus making it seem like no keys were available, which would cause Firefox to not send a client certificate. This patch makes each backend implementation responsible for this rate-limiting, because only they know if it's appropriate to do so (in particular, on Android, `find_objects` doesn't have the same performance concern as on macOS and Windows because rather than searching for certificates and keys, it asks `ClientAuthCertificateManager` for the cached list of certificates and keys that have already been approved for use by the user).
