6b4d46569b alif: Support running the port on the HE core.
The same MicroPython firmware is built for the HE but with slightly
different options, for example no USB.

ccc5935234 alif: Add initial port to Alif Ensemble MCUs.
This commit adds the beginning of a new alif port with support for Alif
Ensemble MCUs.  See https://alifsemi.com/

Supported features of this port added by this commit:
- UART REPL.
- TinyUSB support, for REPL and MSC.
- Octal SPI flash support, for filesystem.
- machine.Pin support.

General notes about the port:
- It uses make, similar to other bare-metal ports here.
- The toolchain is the standard arm-none-eabi- toolchain.
- Flashing a board can be done using either the built-in serial bootloader,
  or JLink (both supported here).
- There are two required submodules (one for drivers/SDK, one for security
  tools), both of which are open source and on GitHub.
- No special hardware or software is needed for development, just a board
  connected over USB.

OpenMV have generously sponsored the development of this port.
