Share the implementation of hashlib across ports

[jepler]

.. many platforms can use mbedtls to implement hashlib.

Compile-tested with pico-w. Tested on feather rp2040 dvi. Enabled on rp2040 for now. Could hypothetically be enabled on other ports.

Alternative to #8719 (ping @anecdata)

I don't know how to test it, however CI doesn't seem to build images for WIZnet boards.

[dhalbert]

@anecdata how are you on this?

[anecdata]

I'm an observer (no relevant expertise), certainly no objections, seems a much more thorough solution than what I originally tried. This originally arose due to someone noticing that websockets in HTTPServer didn't have access to native hashlib on WIZnet / RP2040 boards (someone there should eventually re-test). But I think @Akkiesoft is right that there are no raspberrypi builds, WIZnet or otherwise.

[jepler]

Due to the way the CI optimizes building fewer boards when possible, the rp2040 builds are on a previous Actions run. I think you can get the artifact you'd want for testing from here: https://github.com/adafruit/circuitpython/actions/runs/7305598483?pr=8749

[anecdata]

Performs a similar calculation as in HTTPServer websockets:

EXPAND...

import time

GUID = b"258EAFA5-E914-47DA-95CA-C5AB0DC85B11"
ITERATIONS = 10_000

def hashme():
    key = "dGhlIHNhbXBsZSBub25jZQ=="
    start = time.monotonic_ns()
    for _ in range(0, ITERATIONS):
        response_key = hashlib.new("sha1", key.encode())
        response_key.update(GUID)
    return time.monotonic_ns() - start

import hashlib
duration = hashme()
print(f"{ITERATIONS} iterations in {duration} ns - hashlib")
#import adafruit_hashlib as hashlib
#duration = hashme()
#print(f"{ITERATIONS} iterations in {duration} ns - adafruit_hashlib")

Adafruit CircuitPython 9.0.0-alpha.6-5-g9a7fe7aef4 on 2023-12-23; W5500-EVB-Pico with rp2040
soft reboot

Auto-reload is on. Simply save files over USB to run them or enter REPL to disable.
code.py output:
10000 iterations in 531250000 ns - hashlib

Native hashlib is now present and executes (an order of magnitude faster than the library)... LGTM!

Thanks, @jepler !

[Akkiesoft]

Thank you @jepler !

I tested with W5500-EVB-Pico.

I no longer get the hashlib error when I run the code used in the following Issue URL.
adafruit/Adafruit_CircuitPython_HTTPServer#73

LGTM.

reviewed but did not test, however nothing looks amiss to me :)
