  1. Implement texture_storage_Xd in WGSL 

    This commit implements `texture_storage_Xd` in WGSL, which is similar
to RWTextureXD in HLSL.

It is intresting that `texture_storage_Xd` doesn't take the shader
type as its input argument at all.
Instead, it takes "texel format" enum value as its first template
parameter, which can be found here:
https://www.w3.org/TR/WGSL/#storage-texel-formats

As an example, `texture_storage_2d<rg32uint, read_write>` expects
vec4<u32> as a value type for `Load` and `Store`, where Z-component
will be ignored and treated as zero and W-component will be treated
always as 1. The type `u32` is inferred from the enum value `rg32uint`.
Note that the number of component is always fixed to 4 regardless how
many components are actually stored.
