Make Exception::$trace typed array property
This is a private property, so we are allowed to add a type.
The new declaration of the property is:
private array $trace = [];
This ensures that Exception::getTrace() does indeed return an array.
Userland code that was modifying the property through refleciton
may have to be adjusted to assign an array (instead of null,
for example).
Closes GH-5636.
