Texture loading: reduce memory allocations (#6623)

* rebase

* add methods Ryyjinx.Common EmbeddedResources and SteamUtils

* GAL changes - change SetData() methods and ThreadedTexture commands to use IMemoryOwner<byte> instead of SpanOrArray<byte>

* Ryujinx.Graphics.Texture: change texture conversion methods to return IMemoryOwner<byte> and allocate from ByteMemoryPool

* Ryujinx.Graphics.OpenGL: update ITexture and Texture-like types with SetData() methods to take IMemoryOwner<byte> instead of SpanOrArray<byte>

* Ryujinx.Graphics.Vulkan: update ITexture and Texture-like types with SetData() methods to take IMemoryOwner<byte> instead of SpanOrArray<byte>

* Ryujinx.Graphics.Gpu: update ITexture and Texture-like types with SetData() methods to take IMemoryOwner<byte> instead of SpanOrArray<byte>

* Remove now-unused SpanOrArray<T>

* post-rebase cleanup

* PixelConverter: remove unsafe modifier on safe methods, and remove one unnecessary cast

* use ByteMemoryPool.Rent() in GetWritableRegion() impls

* fix formatting, rename `ReadRentedMemory()` to `ReadFileToRentedMemory()``

* Texture.ConvertToHostCompatibleFormat(): dispose of `result` in Astc decode branch
