This commit modifies the Alif port's Makefile to propagate to child make
tasks the number of parallel jobs to run.
On Ubuntu LTS 24.04, building the Alif port passing a parallel jobs
number to make's command line will result in the command emitting this
warning:
make[1]: warning: jobserver unavailable: using -j1. Add '+' to parent
make rule.
And building the two cores' firmware images using one compile job at a
time instead of the number provided to the command line.

This commit fixes a build issue occurring on systems where the Python
3.x interpreter isn't aliased to 'python' but has a different name
(usually `python3').
The main Linux distribution where this occurs is Ubuntu LTS, where the
Python 3.x interpreter is available as 'python3' since at least two
major versions (so since about five years now). MicroPython's makefile
environment setup file ('py/mkenv.mk') already defines a variable called
'$(PYTHON)' that defaults to 'python3', so the Makefile was updated to
use that instead of hardcoding the interpreter name. Without these
changes, building a firmware image on Ubuntu LTS fails with this error:
make: python: No such file or directory
make: *** [Makefile:95: build-ALIF_ENSEMBLE/firmware.toc.bin] Error 127
This also allows overriding the interpreter name to something else if
there's the need to perform tests with different interpreter versions or
the like.

The resulting `firmware.zip` file is self contained with everything needed
to deploy the firmware, eg over SE UART.

With this new Makefile you can build the following:
make BOARD=MY_BOARD MCU_CORE=M55_HP # build HP firmware/ToC.
make BOARD=MY_BOARD MCU_CORE=M55_HE # build HE firmware/ToC.
make BOARD=MY_BOARD MCU_CORE=M55_DUAL # build HE+HP firmware + ToC.

Includes services to get random numbers, reset SoC, get unique-id, dump SoC
info, and CPU control services.

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.
