enable picogame on Metro RP2350

I didn't realize this wasn't enabled yet on this device. It is required for the code from my turbo pixel dust guide.

I tested it successfully with the code from that guide: https://github.com/adafruit/Adafruit_Learning_System_Guides/blob/main/CircuitPython_Turbo/sand_simulation/metro_rp2350/code.py

Technically only CIRCUITPY_PICOGAME is required for this project, but I added CIRCUITPY_PICOGAME_FRAMEBUFFER as well to match Fruit Jam. Since this device has the HSTX ribbon cable connector it should be able to get the same benefit as Fruit Jam over picodvi though I have tested only the TFT.

@FoamyGuy looks good. Currently For SPI TFT, I'd also add CIRCUITPY_PICOGAME_FAST_DISPLAY = 1. It sends the display strips with DMA in the background, so the TFT path gets faster.

But I plan to move DMA sending to the SPI display bus directly (so displayio can use it as well) in #11468, which will remove FAST_DISPLAY from picogame. So, if you don't have any performance issues, you can leave it as it is.

Thank you! I enabled CIRCUITPY_PICOGAME_FAST_DISPLAY in the latest commit. It does make the rendering and gravity feel smoother.

Happy to have the additional boost since the guides intent is to show off the speed that is now available to us.
