Automatic update from web-platform-tests cpu_performance: Add prototype implementation This CL adds a prototype implementation for a new Web API that exposes some information about how powerful the user device is, targeting applications that will use this information to provide an improved user experience. It is currently implemented behind the runtime flag --enable-features=CpuPerformance. The API exposes navigator.cpuPerformance, which is a small integer number corresponding to the user device's "performance tier" (similarly to navigator.deviceMemory). The prototype implementation simply classifies user devices in five tiers (1-4, denoting increasing performance; 0 for unknown), based on the number of CPU cores. The plan is to allow embedders to override this default with more complicated, implementation-specific behaviour (to be implemented in a subsequent CL).
