Vulkan: SPIR-V Gen: Support mediump/lowp

The mediump and lowp precisions translate to a RelaxedPrecision decoration in SPIR-V. This change implements this decoration and enables SPIR-V generation when emulating Bresenham lines. Prior to this change, Bresenham line emulation resulted in a validation error due to the vertex shader output being without RelaxedPrecision but the fragment shader input (translated by glslang) with it. The function that produces a new id is given a list of decorations to apply, which itself is automatically deriven from the TType where applicable, to minimize the risk of any id missing this decoration.
