Implement support for the drop-shadow filter (#30439)

Browse source 
* Implement support for `drop-shadow`

* Clean up remnant from early attempts

* Fix misleading comments on GenericSimpleShadow
If Servo-specific `style` changes will need to be upstreamed anyway, I might as well fix a thing that had thrown me off!

* Revert "Fix misleading comments on GenericSimpleShadow"

This reverts commit cdc810b826ac082041adc212c24649ee3b86ca0a.

* Clean up an import

* Update test expectations

* Fix missing expectation on Layout 2013
