* misc: Implement address space size workarounds
This adds code to support userland with less than 39 bits of address
space available by testing reserving multiple sizes and reducing
guess address space when needed.
This is required for ARM64 support when the kernel is
configured to use 63..39 bits for kernel space.(meaning only 38 bits is available to userland)
* Address comments
* Fix 32 bits address space support and address more comments
* GPU: Remove CPU region handle containers.
Another one for the "I don't know why I didn't do this earlier" pile.
This removes the "Cpu" prefixed region handle classes, which each mirror a region handle type from Ryujinx.Memory.
Originally, not all projects had a reference to Ryujinx.Memory, so these classes were introduced to bridge the gap. Someone else crossed that bridge since, so these classes don't have much of a purpose anymore.
This PR replaces all uses of CpuRegionHandle etc to their direct Ryujinx.Memory versions.
RegionHandle methods (specifically QueryModified) are about the hottest path there is in the entire emulator, so there is a nice boost from doing this.
* Add docs
