This is required for proper conversion to RGBA8_UNORM or RGBA8_SRGB
surfaces when a backend can target both native and converted ASTC.

This isn't needed anymore, according to Hexagon

Cubemaps are considered layered and to create a texture view the texture
mustn't be a layered texture, resulting in cubemaps being bound as
cubemap arrays. To fix this issue this commit introduces an extra
surface parameter called "is_array" and uses this to query for texture
view creation.

Now that texture views for cubemaps are actually being created, this
also fixes the number of layers created for the texture view (since they
have to be 6 to create a texture view of cubemaps).

- Fixes UI rendering issues in The Legend of Zelda: Breath of the Wild.

Functions which are suppose to crash on non canary builds usually don't return anything which lead to uninitialized memory being used.

* Implement ASTC_2D_10X8 & ASTC_2D_10X8_SRGB
( needed by Mario+Rabbids Kingdom Battle )

* Small placement correction
