mcu-firmware: add support for host side support packages

Browse Source 
In case of some of the MCU firmware types, additional setup on the host
side is required before the target application can be used. Example of
such a requirement is a BLE HCI controller on UART bus (firmware type:
'hci_uart') which, before can be registered in system, needs to be
attached to Bluetooth stack (with e.g. 'btattach').

This includes code for generating hidden packages under 'mcu-firmware'
with all the files required for host side support (stored in directory
with the same name as firmware type, under local 'files' directory),
for a selected MCU firmware. For example, below tree:

  ./feeds/mcu/mcu-firmware/files/hci_uart/etc/...

would result in creation of new package 'zephyr-hci_uart-host-support',
included in dependencies lists for all MCU firmware versions of the
'hci_uart' type, with everything from '.../files/hci_uart/'.
