Add a pssr toggle for ps5 pro

add a PSSR upscaling toggle and a 120fps performance mode. Currently On PS5 Pro, the only upscaling options are Bilinear and TAAU There is no PSSR toggle and the game is capped at 60fps. Why it matters: PS5 Pro hardware supports PSSR and 120fps output, so Bedrock is not using the console's headline upscaling / frame-rate capabilities. A PSSR toggle would let players choose Sony's upscaler over Bilinear/TAAU, and a 120fps mode would match what other PS5 Pro titles offer. Thank you for considering it.
