feeds: mcu: introduce 'mcu-firmware' package

Browse Source 
The new 'mcu-firmware' package will provide binary firmware dedicated
for MCU embedded on Wi-Fi boards (and also standalone, e.g. USB based),
supported by the OpenWrt/OpenWiFi projects. Currently, only Zephyr RTOS
based sample firmware ('BLE HCI controller' and 'hello world') files are
provided, for Wi-Fi boards and one standalone development module, listed
below:

- CIG WF-196 (Nordic nRF52833, UART bus)
- EdgeCore EAP102 (Nordic nRF52840, USB bus)
- Nordic nRF52840 Dongle (Nordic nRF52840, USB bus)

Different firmware types planned in future include Nordic's nRF Connect
SDK, OpenThread and others.

The Zephyr based firmware comes from a custom fork available in GitLab:
'https://gitlab.com/pepe2k/zephyr' (firmware in this package were built
from a v3.3.0 release based branch 'zephyr-v3.3.x__mcu-on-wifi-boards').

MCU firmware from this package is compatible only with OpenWrt/OpenWiFi
generic MCU support stack which, among others, assumes availability of
compatible bootloader (MCUboot is currently the only one supported) and
e.g. multiple firmware slots. MCUboot fork development takes part in git
repository hosted in GitLab: 'https://gitlab.com/pepe2k/mcuboot/'.
