renderer: add area sampling scaling method (#201)

Adds Area Sampling to the list of scaling options. Works well to achieve a high-quality, smooth super-sampling effect. Dolphin has had this for a while and so has Ryujinx, so lui decided to port it.

Adapted from these two PRs:
https://github.com/Ryujinx/Ryujinx/pull/7304
https://github.com/dolphin-emu/dolphin/pull/11999
