Jeroen Bakker 91bfd8dfc4 ShaderC: Remove global locale lock
This is a backport of a patch in SPIRV-Tools that will allow faster
parallel compilation.

See https://github.com/KhronosGroup/SPIRV-Tools/issues/5802 for the
original report.

The issue is that SPIRV tools used a stringstream to convert an uint32_t
to a string when optimizing shaders. stdlib provided by the platform
would set a locale and would mutex globally, making parallel compilation
fully lock. Compilation lead times were as fast as single threaded
compilation.
