Use the AddSpirvBlockDecoration transform to do this.
Add expected results for all of the new E2E tests. The arrayLength()
tests all fail as this is not yet implemented for the GLSL
backend. The other tests all pass except two that assign whole structs
to buffers, which is also a pre-existing issue.

These two transforms previously assumed that the argument to
arrayLength had the form `&struct_var.array_member`. We now also need
to handle the case where it is just `&array_var`.

Generate a uniform buffer that will receive the lengths of all storage
buffers, and use this to implement calls to arrayLength(). The
transform is provided with a set of mappings from storage buffer
binding points to the corresponding index into the array of buffer
lengths. The transform reports whether it generated the uniform
buffers or not.
Use this transform from the MSL sanitizer, using the binding number as
the index into the array. This matches the behavior of spirv-cross,
and so works with how Dawn already produces this uniform buffer.

And fix issues where global variables would not be emitted unless they were transitively referenced by an entry point.
This change requires crbug.com/tint/697 to be fixed before landing.
