Currently maturin hardcodes minimal supported interpreter versions based on pyo3 versions, it'd be nice if this information is encoded in cargo package metadata of pyo3 and pyo3-ffi so we can make it future-proof in maturin.

For example:

[package.metadata.cpython]
version = ">=3.7,<3.14"

[package.metadata.pypy]
version = ">=3.9,<3.11"

Seems like a good idea, I guess these are then available to maturin via cargo metadata?
