Struct TexelAddress

struct TexelAddress {
    coordinate: Handle<Expression>,
    array_index: Option<Handle<Expression>>,
    sample: Option<Handle<Expression>>,
    level: Option<LevelOfDetail>,
}

Values needed to select a particular texel for ImageLoad and ImageStore.

When this is used in code paths unconcerned with the Restrict bounds check policy, the LevelOfDetail enum introduces an unneeded match, since level will always be either None or Some(Direct(_)). But this turns out not to be too awkward. If that changes, we can revisit.
