PHP 8.2 | Various tests: explicitly declare properties

Dynamic (non-explicitly declared) property usage is expected to be deprecated as of PHP 8.2 and will become a fatal error in PHP 9.0.

There are a number of ways to mitigate this:
* If it's an accidental typo for a declared property: fix the typo.
* For known properties: declare them on the class.
* For unknown properties: add the magic `__get()`, `__set()` et al methods to the class or let the class extend `stdClass` which has highly optimized versions of these magic methods build in.
* For unknown _use of_ dynamic properties, the `#[AllowDynamicProperties]` attribute can be added to the class. The attribute will automatically be inherited by child classes.

This commit addresses a number of issues in the "known property" category within the test suite.
