Expose `PyRuntimeInfo` from `py_binary` and `py_test` rules

This allows targets that depend on an executable Python target to see what runtime was chosen from the toolchain. The returned `PyRuntimeInfo` provider is the same type of value as what's returned by the `py_runtime` rule.

For example, the path to the system interpreter (if not using an in-workspace interpreter) can be accessed from a dependency as `mydep[PyRuntimeInfo].interpreter_path`. The Python major version for a target can also indirectly be obtained from the version of its runtime, as `mydep[PyRuntimeInfo].python_version`.

Fixes #7805.
