fix: add inflight window setting to the clickhouse bridge

This commit makes sure the inflight window setting is present for the
clickhouse bridge. It also changes emqx_resource_schema that previously
removed the inflight window setting from resources with query mode
`always_sync`. We don't need to do that because all bridges that uses
the buffer worker queue will get async call handling even if the bridge
don't support the async callback.
