Subject: [PATCH 6/8] Implement sceKernelMapDirectMemory2 (#2940)

* Implement sceKernelMapDirectMemory2

Behaves similarly to sceKernelMapDirectMemory, but has a type parameter.

* Simplify

No need to copy all the MapDirectMemory code over, can just call the function, then do the SetDirectMemoryType call

* Clang

Subject: [PATCH 8/8] Proper error handling for MapMemory errors (#2938)

* Properly handle ENOMEM error return in MapMemory

Needed for Assassin's Creed Unity to behave properly.

* Change error message

If I left the message as-is, we'd probably see inexperienced people claiming the assert means your device needs more memory, which is completely false.

* Clang

You know you're doing something right when Clang complains.

* Attempt to handle MemoryMapFlags::NoOverwrite

Based on my interpretation of red_prig's descriptions. These changes are untested, as I'm not able to test right now.

* Fix flag description

* Move overwrite check to while condition
