DevTools: CPUFlameChart: stick function entry color to the function name and url.

DevTools: CPUFlameChart: stick function entry color to the function name and url.

The old color generator had the dependency from line number too and it was a bad idea because
after a change in the source file the entry would change the color.

Also the entry colors had implicit dependency from the order of processing.
