  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.
