Add the API to validate the BSS before roaming to it. This API will check if other vdevs are already connected to the BSS, if concurrency is allowed, and if channel is allowed for the current HW mode. Keep the new changes under the interface_mgr feature flag. Change-Id: I280e95b0a30c08fe4037295330628b79d22acf5f CRs-fixed: 2774543
