Python extension modules now depend on the python library by default

Python extension modules are usually expected to link to the python library and/or its headers in order to build correctly (via the default embed: false, which may not actually link to the library itself). This means that every single use of .extension_module() needed to include the dependencies: py_installation.dependency() kwarg explicitly.

In the interest of doing the right thing out of the box, this is now the default for extension modules that don't already include a dependency on python. This is not expected to break anything, because it should always be needed. Nevertheless, py_installation.dependency().partial_dependency() will be detected as already included while providing no compile/link args.
