Texture rework

[SamoZ256]

This PR reworks textures:

• Depth and array layers are treated separately
• Stride is calculated for non-linear textures
• Texture views are separated into a their own class
• A very primitive texture viewer

TODO:

• Rework layout conversions
• Support mips
• Calculate layer stride properly

This PR causes additional vertex explosions in Super Mario Odyssey for unknown reasons.
