Implement psr/container 1.1

This PR proposes to upgrade Pimple's PSR-11 implementation with parameter type declarations from `psr/container` 1.1.

Since the `Container` class is `final`, I have also added a return type to the `has()` method as a preparation for version 2 of the interfaces. Unfortunately, the `ServiceLocator` class is not final, so I could not add the return type here as that would be a BC break. If I'm not mistaken, this would be the only change necessary for `psr/container` 2.

Run the tests on PHP 8.0

The test suite is currently run on PHP 7.2, 7.3, 7.4 and 8.1-dev (`nightly`). I think it should be run on PHP 8.0 too, which is the current stable PHP release.
