Adding the stm32h5 pwm driver. This is almost an exact copy of the stm32h7 pwm driver. I confirmed the timers for the h5 are version v2 and added the preprocessor definition. This commit was tested on a stm32h5 nucleo-h563zi development board. Necessary board files and a pwm config have been added. Added pin mappings for all timer outputs.

Added documentation regarding nucleo-h563zi:pwm config.
Removed CONFIG_STM32H5_PWM guard at the top. Fixed IRQs for tim1 and tim8. Added H5 to list of Timer IP v2 timers.
Conditionally compile stm32_serial.c.
Add stm32_pwm.c to CMakeLists.txt
