MDL-79890 core: Stop using get_class() without args

PHP 8.3 deprecates the use of `get_class()` without arguments. The
following alternatives should instead be used as appropriate:

- `get_class($this)` - The equivalent for instance methods
- `self::class` - The current class

Note that the behaviour of `get_class()` in a static method was
equivalent to `self::class` and _not_ `static::class`. That is to say
that the previous behaviour did not respect late static binding.
