[TASK] Use PSR-17 StreamFactoryInterface in ActionController

The extbase ActionController is already using the
PSR-17 ResponseFactoryInterface for creating PSR-7
responses. The body however was still set in a
PSR-7 "fashion". This is now changed to also use
PSR-17 for setting the response body. More precisly,
the PSR-17 StreamFactoryInterface is used explicitly
instead of letting the body stream be created implicity
by getBody().

The PSR-17 StreamFactoryInterface is therefore
from now on available in every extbase action controller.

Besides the `createStream` method, the interface
also features `createStreamFromResource` and
`createStreamFromFile` methods. The latter is really useful
for responses that contains files, e.g. a ZIP download.

This also adjusts the corresponding changelogs
and replaces examples, which used the internal
`HtmlResponse` class.
