NUCLEO_WB55RG: add Cordio HCI and Transport Layer driver

The STM32WB Coridio driver includes:
- the Cordio HCI driver handling the reset sequence. During reset sequence
the TX POWER level is set and the BD address is defined if found in OTP
or option bytes. The rest of the sequence is based on the standard CORDIO
HCI driver example.
- The Transport Layer part handles sending and receiving messages to the
WB controller running on cortex-M0 of the STM32WB target. The messages
are shared through shared memory and mailboxes system based on IPCC HW.
