Add prebuilt WICED libraries for the PSoC 6 boards with WICED radios:
* TARGET_CY8CKIT_062_4343W
* TARGET_CY8CKIT_062_WIFI_BT
* TARGET_CY8CPROTO_062_4343W
* TARGET_CYW943012P6EVB_01
Add required extra labels to the PSoC 6 targets in targets.json:
(PSOC6_01/02 labels are used during the library compilation).
Connection status issue corrected. If the link layer status changes,
the connection status callback is now called correctly.
mbedtls headers from library are removed and the mbed-os one's are used.
