compiler: Allow the explicit_stride of aoa types to be zero

Browse source 
The explicit stride doesn't have to be defined to aoa and therefore can be
zero in some cases, like in arrays of arrays of uniform blocks.

Resolves crash with spec@arb_gl_spirv@execution@ubo@aoa-2.shader_test piglit test for virgl.
