SRGBFramebufferTest: Add test that used to fail on Vulkan. This commit adds a test that reproduces a Vulkan validation error found in several suites of the Chromium CI. The error was caused by enabling the VK_KHR_image_format_list extension on SwiftShader and thus exposing the GL_EXT_sRGB_write_control GL extension. Commit bd19620fcd599947a2fada3e02061d02d690d9eb reverted the change and disabled the extension for all platforms besides AMD and ARM. The issue was fixed in angle by either of the following commits: cf090996c7850074d76ce8408af4661a3c91e5e2 e70a1444af85c77a39e82a69569f723098c8d37c To reproduce the Vulkan validation error, both commits need to be reverted.
