HLSL: Add min*{float,int,uint} types

Browse Source 
These HLSL types are guaranteed to have at least the given number of bits, but may have more.

min{16,10}float is mapped to EbtFloat at medium precision -> SPIRV RelaxedPrecision
min{16,12}int and min16uint are mapped to mediump -> SPIR-V RelaxedPrecision
