[PATCH v3 2/5] vkd3d-shader/spirv: Handle signature element mask left shift in spirv_compiler_emit_output().

[Conor McCarthy]

From: Conor McCarthy

Element masks can have a left shift in DXIL, but these must start at
bit 0 in the register info. The SPIR-V declaration will either be a
builtin or have SpvDecorationComponent.
