Hans-Kristian Arntzen 2ed171e525 GLSL/MSL: Implement 8-bit part of VK_KHR_shader_float16_int8.
Storage was in place already, so mostly just dealing with bitcasts and
constants.

Simplies some of the bitcasting logic, and this exposed some bugs in the
implementation. Refactor to use correct width integers with explicit bitcast opcodes.
