[TASK] Extend RecordInterface

The RecordInterface is extended to require
implementations to implement the `getRawRecord()`
and `getSystemProperties()` methods as well
as the PSR-11 `ContainerInterface`.

This allows to change RecordFactory's `createRecord()`
method to return the interface instead of the
`Record` object. This will come in handy e.g.
for the already existing `Page` object, which
can now be used without extending `Record`.

By using the `ContainerInterface` we allow
access to the record and its properties via
the has() and get() methods, which is supported
since Fluid 4.0: https://github.com/TYPO3/Fluid/issues/1001.
