glsl: Add IR lisp for GLSL ES 3.00 pack/unpack functions

Browse source 
For each of the following functions, add a declaration to
builtins/profiles/300es.glsl and create new file
builtins/ir/${funcname}.ir:

  packSnorm2x16  unpackSnorm2x16
  packUnorm2x16  unpackUnorm2x16
  packHalf2x16   unpackHalf2x16
