stm32wb55 support

[kasjer]

Describe the PR
This PR adds support for STM32WB55 MCU.
nucleo-wb55rg board is also added.

This MCU has stm32_fsdev FS device USB block same as some others ST devices (F1, Gx)

Additional context
ST provided headers have incorrect value of USB_PMAADDR that is used in stm32_fsdev code.
Issue is filed on their github.
So for now this is fixed on TinyUSB side.

It is very minor, I think the family name should be stm32wb 55 is too specific. Other than that, everything looks great.

I agree, let me change it. I used 55 because this is the only part that has USB.

oh I didn't know that, but I guess that could be changed in the future. It is still better to rename it

I have not problem with changing family it to WB only.
btw. while you are on it, maybe you can suggest how to set UF2_FAMILY_ID = in make file.
It's new to me, and I did not dwell on the subject really.

It is the ID for DFU example with board pre-flashed with uf2 bootloader such as https://github.com/adafruit/tinyuf2 . The ID is managed by uf2 specs, ID for stm32wb is as follows. It is optional, for convenient purpose only. So far most of the board is devkit with dedicated jtag/swd debugger.

Family changed to STM32WB.
I also change board name to stm32wb55nucleo to match other nucleo boards naming convention.

perfect, thank you very much for your PR.
