writer/spirv: Support declaring workgroup variables with 0 initializer

This patch adds an option to declare the workgroup variables with zero
initializer in Build() instead of transform::ZeroInitWorkgroupMemory
in Sanitize(). This option will be enabled when the Vulkan extension
VK_KHR_zero_initialize_workgroup_memory is enabled on the API side.
