On macOS and Windows, the underlying implementations of the OS APIs that provide access to keys and certificates are not necessarily thread-safe. Before this patch, essentially all calls into osclientcerts would be synchronously forwarded to a single background thread. Unfortunately, the cost of dispatching and waiting for all of these events was non-trivial, particularly when the vast majority of them should essentially be no-ops (e.g. when NSS is looking for CA certificates or trust information, etc.). This patch reworks the implementation to only dispatch operations involving OS APIs to the background thread. Differential Revision: https://phabricator.services.mozilla.com/D246520
