This commit adds preliminary support for ST's new STM32N6xx MCUs.
Supported features of this MCU so far are:
- basic clock tree initialisation, running at 800MHz
- fully working USB
- XSPI in memory-mapped mode
- machine.Pin
- machine.UART
- RTC and deepsleep support
- SD card
- filesystem
- ROMFS
- WiFi and BLE via cyw43-driver (SDIO backend)
Note that the N6 does not have internal flash, and has some tricky boot
sequence, so using a custom bootloader (mboot) is almost a necessity.

This commit adds initial support for STM32H5xx MCUs. The following
features have been confirmed to be working on an STM32H573:
- UART over REPL and USB CDC
- USB CDC and MSC
- internal flash filesystem
- machine.Pin
- machine.SPI transfers with DMA
- machine.ADC
- machine.RTC
- pyb.LED
- pyb.Switch
- pyb.rng
- mboot

The default stm32lib remains lib/stm32lib, but it can now be easily
overriden at build time by specifying STM32LIB_DIR, or STM32LIB_CMSIS_DIR
and STM32LIB_HAL_DIR.
