[GPU] Separate range arguments for fixed16 RG and RGBA in GetResolveInfo 

On Vulkan, when snorm16 in unsupported, these formats may be emulated as float16, which natively can represent a wide range of numbers including -32 to 32 with blending. However, R16G16_SNORM and R16G16B16A16_SNORM are two separate formats, which may have different support on the device.
