Migrate all tests over to using Default Struct Layout

Browse Source 
The WGSL spec has been updated with 'Default Struct Layouts':
https://github.com/gpuweb/gpuweb/pull/1447

This removes the `[[offset(n)]]` decoration, and replaces it with two optional decorations: `[[size(n)]]` and `[[align(n)]]`, and a sensible set of sizes and alignments for each type.

Most `[[stride(n)]]` decorations have also been removed from arrays.
