* Texture: Fix layout conversion when gobs in z is used with depth = 1
The size calculator methods deliberately reduce the gob size of textures if they are deemed too small for it. This is required to get correct sizes when iterating mip levels of a texture.
Rendering to a slice of a 3D texture can produce a 3D texture with depth 1, but a gob size matching a much larger texture. We _can't_ "correct" this gob size, as it is intended as a slice of a larger 3D texture. Ignoring it causes layout conversion to break on read and flush.
This caused an issue in Tears of the Kingdom where the compressed 3D texture used for the gloom would always break on OpenGL, and seemingly randomly break on Vulkan. In the first case, the data is forcibly flushed to decompress the BC4 texture on the CPU to upload it as 3D, which was broken due to the incorrect layout. In the second, the data may be randomly flushed if it falls out of the cache, but it will appear correct if it's able to form copy dependencies.
This change only allows gob sizes to be reduced once per mip level. For the purpose of aligned size, it can still be reduced infinitely as our texture cache isn't properly able to handle a view being _misaligned_.
The SizeCalculator has also been changed to reduce the size of rendered depth slices to only include the exact range a single depth slice will cover. (before, the size was way too small with gobs in z reduced to 1, and too large when using the correct value)
Gobs in Y logic remains untouched, we don't support Y slices of textures so it's fine as is.
This is probably worth testing in a few games as it also affects texture size and view logic.

* Maybe a bit better
* GPU: Remove swizzle undefined matching and rework depth aliasing
@gdkchan pointed out that UI textures in TOTK seemed to be setting their texture swizzle incorrectly (texture was RGB but was sampling A, swizzle for A was wrong), so I determined that SwizzleComponentMatches was the problem and set on eliminating it. This PR combines existing work to select the most recently modified texture (now used when selecting which aliased texture to use) with some additional changes to remove the swizzle check and support aliased view creation.
The original observation (#1538) was that we wanted to match depth textures for the purposes of aliasing with color textures, but they often had different swizzle from what was sampled (as it's generally the identity swizzle once rendered). At the time, I decided to allow swizzles to match if only the defined components matched, which fixed the issue in all known cases but could easily be broken by a game _expecting_ a given swizzle, such as a 1/0 value on a component.
This error case could also occur in textures that don't even depth alias, such as R11G11B10, as the rule was created to generally apply to all cases.
The solution is now to fail this exact match test, and allow the search for an R32 texture to create a swizzled view of a D32 texture (and other such cases). This allows the creation of a view that mismatches the requested format, which wasn't present before and was the reason for the swizzle matching approach.
The exact match and view creation rules now follow the same rules over what textures to select when there are multiple options (such as a "perfect" match and an "aliased" match at the same time). It now selects the most recently modified texture, which is done with a new sequence number in the GpuContext (because we don't have enough of these).
Reportedly fixes UI having weird coloured backgrounds in TOTK. This also fixes an issue in MK8D where returning from a race resulted in the character selection cubemaps being broken. May work around issues introduced by the "short texture cache" PR due to modification ordering, though they won't be truly fixed.
Should allow (#4365) to avoid copies in more cases. Need to test that.
I tested a bunch of games #1538 originally affected and they seem to be fine. This change affects all games so it would be good to get some wide testing on it.
* Address feedback 1, fix an issue
* Workaround: Do not allow copies for format alias.
These should be removed when D32<->R32 copy dependencies become legal
* 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
* GPU: Keep sampled textures without any pool references alive
Occasionally games are very wasteful and clear/write to a texture without ever sampling it. As rendered textures in NVN games seem to all have overlapping memory ranges, the texture will eventually get overwritten.
Normally, this would trigger a removal from the auto delete cache, but a pool entry would keep the texture alive. However, with these textures that are never used, they will get deleted immediately and recreated on the next frame.
This change makes it so the ShortTextureCache can keep textures that have naver had a pool reference alive for a few frames, so they're not constantly being created and deleted.
This improves performance in Zelda BOTW a little.

* GPU: Fix errors handling texture remapping
- Fixes an error where a pool entry and memory mapping changing at the same time could cause a texture to rebind its data from the wrong GPU VA (data swaps)
- Fixes an error where the texture pool could act on a mapping change before the mapping has actually been changed ("Unmapped" event happens before change, we need to signal it changed _after_ it completes)
