Description
The #include <array> line in gfx/angle/checkout/include/GLSLANG/ShaderLang.h is not working on MacOS.
This is breaking ./mach build on a fresh servo clone (servo commit: 6bad65a5a16c5a90b09fe8d0441c1d473e46e060)
--- stderr
gfx/angle/checkout/include/GLSLANG/ShaderLang.h:13:10: fatal error: 'array' file not found

Research direction
Start with gfx/angle/checkout/include/GLSLANG/ShaderLang.h and the binding-generation path at mozangle's build.rs:371. Reproduce the failure with ./mach build on a fresh macOS Servo clone at commit 6bad65a5a16c5a90b09fe8d0441c1d473e46e060, then trace why the C++ standard header is not found. Done means the fresh clone builds without the missing 'array' diagnostic.
