CefSharedProcessMessageBuilder supports creation of a CefProcessMessage backed by a CefSharedMemoryRegion. Performance tests comparing the existing ArgumentList approach and the new SharedMemoryRegion approach have been added to cefclient at http://tests/ipc_performance. CefMessageRouter has been updated to use SharedMemoryRegion as transport for larger message payloads. The threshold is configurable via |CefMessageRouterConfig.message_size_threshold|. To test: run `ceftests --gtest_filter=SendSharedProcessMessageTest.*:SharedProcessMessageTest.*:MessageRouterTest.Threshold*`
