Code is mainly just copy/pasted from kernel/util/xex2.cc, I've tried fixing it up to work better in a class, but there's probably some things I missed.
Also includes some minor improvements to the XEX loader, like being able to try both XEX keys (retail/devkit) automatically, and some fixes to how the base address is determined.
(Previously there was code that would get base address from optional header, code that'd get it from xex_security_info, code that'd use a stored base address value...
Now everything reads it from a single stored value instead, which is set either from the xex_security_info, or if it exists from the optional header instead.
Maybe this can help improve compatibility with any weird XEX's that don't have a base address optional header?)
Compressed XEX loader also has some extra checks to make sure the compressed data hash matches what's expected.
Might increase loading times by a fraction, but could save reports from people unknowingly using corrupt XEXs.
(still no checks for non-compressed data though, maybe need to compare data with xex_security_info->ImageHash?)
[Vulkan] Don't use power of two for mip width/height calculation for host textures.
[Vulkan] Add more Vulkan error logging.
[Vulkan/GPU] Rudimentary texture dumping.
- [GPU] Precalculate memory byte usage for base mip (and any additional mip levels).
- [GPU] Change TextureCache::WatchCallback so that if it's fired multiple times for the same texture it does not assert.
- [GPU] Add write watches for texture memory associated with additional mipmap levels.
Fix broken mesh polygons in the Call of Duty series. Also remove saturation of D3DCOLOR when packing because values near 3 may be accepted, while unpacking D3DCOLOR gives values near 1.
[Vulkan] Track both texture block height and texture block vertical pitch.
[Vulkan] Only convert the necessary visible height on texture uploads.
[Vulkan] Fix write watch on texture data so it properly only covers mip 0 data.
