📄 Description

Adds support for the larger PS4 Pro memory size when enabled. The value is not confirmed to be exact with hardware but aligns with expectations and at least gets games that utilize the extra memory running under Pro mode for now.

I also added an assert when the GPU page manager tries to track memory that is not mapped to the GPU, as I ran into a problem related to this while testing PS4 Pro mode. Currently when this happens it silently re-protects non-GPU memory, which can fail in confusing ways later as writes to that memory will be ignored by the signal handler and fail. Adding an assert makes it more obvious what happened.
