vkd3d-shader/spirv: Always use a 64-bit write mask for IMMCONST64 src params.

Browse Source 
There is no way to tell in spirv_compiler_emit_load_reg() if the write
mask is 64-bit. All loads are 32-bit except for IMMCONST64 and SSA, and
the latter ignores the mask, so the only issue lies with IMMCONST64.
