spirv: Implement OpArrayLength for OpenGL

Uses same NIR intrinsic as glsl_to_nir.  Make it an option so it is
easy later to move Vulkan drivers incrementally to use it.

Fixes piglit test spec/arb_gl_spirv/execution/ssbo/unsized-array-length.

Backported from f65750d2215 ("spirv: Implement OpArrayLength for OpenGL").

Closes: https://gitlab.freedesktop.org/mesa/mesa/-/issues/3691
Fixes: 15e43907 ("iris: Enable ARB_gl_spirv and ARB_spirv_extensions")
