[feature] Added support for STLINK-V3PWR

[Sazerac4]

I propose the integration of stlink-V3PWR.
I'm not sure about the name : STLINK_USB_PID_STLINK_V3P

This PR is a follow-up to #1388

[Nightwalker-87]

@florrant Is this version verified to be functional with the related device, or is this contribution yet incomplete?
I am not able to test this without the respective hardware.

I got the "stlink-v3pwr" and this patch allow me to flash my programs:

• st-flash --reset --format=ihex write ./program.hex

It is work with a STM32U575 too :

• st-flash --reset --format=ihex write *.hex
