Add support for nucleo-h723zg

Browse Source 
Mostly copy of stm32h743nucleo.
Linker script generated by STM32CubeIDE.

Since this device has only one HS USB
board.h contains few defines that map on
board HS USB to FS because there is no
ULPI chip mounted on Nucleo board.

For FreeRTOS build:
Set interrupt priority for HS always and for FS if exists.
