Add validation to the maximum inter-shader stage variable location

This patch adds the validation rules on the maximum inter-shader
stage variable locations. According to Vulkan SPEC, "Each effective
Location must have a value less than the number of location avaiable for
the given interface", and according to Table 18 "Shader Input and Output
Locations", the number of available vertex output locations is
maxVertexOutputComponents / 4, and the number of available fragment input
locations is maxFragmentInputComponents / 4.
