This should be required for Vulkan support via SwiftShader but I wasn't able to test/confirm it yet (according to strace Chromium never tried to load that file). The relevant flags for using Chromium with SwiftShader are documented at [0] and SwiftShader's ANGLE documentation [1] mentions the relevant files. See also [2], [3], and [4] for more details.
