Sort out target environments used in different components.

SPIRV-Tools has its own target environment definition, and public
shaderc API has its own. A new one is added into Compiler in
shaderc_util, for better isolation.

Now shaderc_util::Compiler's interface accepts target environment,
not glslang messages anymore. All the conversion to glslang messages
are done in the implementation now.
