Macos wheels use current system instead of minimum compatible system as plaftform tag

Feature Request

I noticed a difference between how bdist_wheel from the wheel package choose the platform tag on macos and how poetry-core does it.

In poetry-core:

tag = (sys_tag.interpreter, sys_tag.abi, sys_tag.platform)

Where sys_tag.platform comes from packaging.tags.sys_tags.

In wheel:

plat_name = get_platform(self.bdist_dir)

Where get_platform() calls calculate_macosx_platform_tag.

This routine loop through all .dylib and .so files in the wheel and get the minimum macos system version using extract_macosx_min_system_version.

This allows build systems such as cibuildwheel on github actions to build wheels using macos-latest that are compatible with old systems (see an example here).

It would be nice if poetry could provide the same kind of thing :) Packaging is complicated though, so I might be missing something.

Review the referenced poetry-core wheel builder around wheel.py and compare its sys_tags platform handling with wheel's get_platform and macOS helpers, especially calculate_macosx_platform_tag and extract_macosx_min_system_version. Done means Poetry-generated macOS wheels use the minimum compatible system version from their contents rather than only the current system platform tag.
