Add type to OverridableConstant 

The overridable constants type can only be deducted from shader, those
passed into `record<USVString, GPUPipelineConstantValue> constants;`
are all double. In dawn pipeline (vulkan backend for exmaple) we need to
do type cast for these double values and passed in to native API
