[SPIR-V] Invalid spirv: ResourceDescriptorHeap, ConstantBuffer, vk::RawBufferLoad

Description
Invalid spirv generated with this simple shader:

Steps to Reproduce

struct Constants
{
	uint info;
};

[[vk::push_constant]] Constants g_constants;

struct Info
{
	uint64_t address;
};

void pixel_main(out uint target0 : SV_Target0)
{
    ConstantBuffer< Info > info = ResourceDescriptorHeap[g_constants.info];
    target0 = vk::RawBufferLoad< uint >(info.address);
}

Actual Behavior

fatal error: generated SPIR-V is invalid: [VUID-StandaloneSpirv-None-10684] Invalid explicit layout decorations on type for operand '18[%_ptr_Function_type_ConstantBuffer_Info]', the Function storage class has a explicit layout from the Block decoration.
  %24 = OpVariable %_ptr_Function_type_ConstantBuffer_Info Function
