GLSL: a grab bag of texture fixes.

Use imageSize() on images, not textureSize().
In GLSL, the LOD parameter to textureSize() is mandatory for
sampled textures, so emit a default 0 if not supplied. (Also, don't pack
the level into the coords argument; that's an HLSLism.)
GLSL returns the array size of array textures in the final component
of textureSize(); remove it for WGSL.
Write the subtype of storage images correctly (uimage*, iimage*, etc).
This required a bit of cleanup to move "writeonly" ahead of subtype
emission.
