Fix regression in Tomb Raider Legends
...
Need to make sure a buffer size check happens before the buffer is
accessed - since the game calls sceAtracSetDataAndGetID with both buffer
and bufferSize as 0, and it expects to receive TOO_SMALL and not a
memory exception.
Thanks to @sum2012 for quick investigationh help.

Memory::IsValidAddress: Consider VRAM with a kernel flag invalid.
...
We don't have it mapped in our memory map, so this can actually crash
checked reads like Read_U32.
Since it isn't mapped, and it can't possibly be valid in retail PSP
games to access VRAM this way, I don't think this will cause any
problems.
However, if it does, we'll have to add the corresponding mappings to the
memory map.

especially. Play it safe.

A bit more GetPointer cleanup.
...
Probably not worth it for performance reasons, but some semantic cleanup
is good, especially the accidental GetPointer -> writable casts without
using GetPointerWrite.
Using Unchecked on already checked pointers, or when we'd crash anyway
if it returned nullptr, is good for clarity.

* Add range checks in replaced memcpy/memset functions.
Keep seeing especially Replace_memcpy as a semi-rare crash in the
reports. Hopefully this will take care of it, though if games hit this,
they're probably on their way to failing somehow anyway.

We considered any texture from kernel memory "reliable", which is wrong
since games can allocate out of the upper half of kernel RAM, which is
called "volatile" memory.
