intel/fs: make sure shuffle is lowered to supported types

intel/fs: make sure shuffle is lowered to supported types

On XeHP there are restrictions on types of source and destinations
with float types. As shuffle is implemented using MOV we need to make
sure we lower it to supported types.

This fixes tests like :

    dEQP-VK.subgroups.arithmetic.framebuffer.subgroupexclusivemax_vec4_vertex
    dEQP-VK.subgroups.arithmetic.framebuffer.subgroupexclusivemul_f16vec3_vertex
