Subject: [PATCH] GCC: Remove double declaration of ContextSet

After the CL
https://chromium-review.googlesource.com/c/angle/angle/+/2965780
the build with GCC failed with error:
/third_party/angle/src/libANGLE/Display.h:325:37: error: declaration of
'typedef class std::__1::set<gl::Context*> egl::Display::ContextSet'
changes meaning of 'ContextSet' [-fpermissive]
/third_party/angle/src/libANGLE/Display.h:75:7: note: 'ContextSet'
declared here as 'using ContextSet = class std::__1::set<gl::Context*>'

To fix the error the double declaration of ContextSet is removed.
