glslang: Add API override of version and profile for testing purposes. From Lei Zhang <antiagainst@google.com>.

Browse source 
Add defaultProfile and forceDefaultVersionAndProfile into shader
compilation interface.

forceDefaultVersionAndProfile allows us to force parsing the input
shaders using defaultVersion and defaultProfile, regardless of
the #version directive in input shaders.

These two parameters enables us to programmatically invoke glslang
but specify version and profile from somewhere else like command
line.
