Ryan Harrison cf1bf1c6ae Update external/ to SPIR-V 1.5
Rolled the hashes used for glslang, SPIRV-Tools, and SPIRV-Headers to
HEAD, which includes the update to 1.5.

Added passing '--amb' to glslang, so I didn't have to explicitly set
bindings in a large number of test shaders that currently don't, and
now glslang considers them invalid.

Marked all shaders that no longer pass spirv-val as .invalid.
