fix: platform tag detection

[mayeut]

• use struct.calcsize("P") == 4 rather than sys.maxsize == 2147483647 to check for 32bit interpreter
  (same as stdlib platform.architecture default implementation)
• extend the 32bit check to linux-aarch64 => linux-armv7l (fixes AssertionError: would build wheel with unsupported tag ('cp38', 'cp38', 'linux_aarch64') #367)

The first one fixes platform tag detection with GraalPy (xref pypa/packaging#710 / pypa/packaging#711)

Could you add test coverage for the new lines not covered yet (the ones codecov pointed out)?

[mayeut]

I'll try but it's not covered right now so it's not as easy as just extending existing test:

Done

Thanks – one more thing: add a descriptive note (and attribution to yourself) to the changelog (docs/news.rst).
