[tracing] Add separate dump provider for sql connection
The sql connection memory dump is not thread safe since the connections
can get deleted while a dump is happening. To make this thread safe,
this CL introduces a dump provider class owned by the connection. This
class holds a lock when dumping and deleting the database. Also, to
workaround thread safe dump provider registration, it uses the
UnregisterAndDeleteDumpProviderAsync api added in crrev.com/1430073002.
