This reverts commit 41261d95a417bb3a121c162154d441433705a237. This reverts commit 7c9accb6534d4cde050555b8091b434dc7e4d218. Instead of trying to work around all of the potential semicolon issues in glslang, making it conform to Chromium's style, mark the code explicitly as non-chromium in the BUILD.gn, so chromium doesn't attempt to enforce its style rules on glslang. Fixes #1931
