Current LED color changes are abrupt. This CL adds a new function which steps from one color (some RGB combo) to another gradually. When the new or old color is white, then precomputed steps computed from HSI space are used. Other transisions involving either just red/green use linear steps computed dynamially based on the total change. This CL also creates a new task for the LED code so that the color transitions won't hold off other hook tasks for too long a period of time. Changed the LED tick time to be 500 msec as it's no longer tied to the hook tick. BUG=b:35584895 BRANCH=eve TEST=Using EC console command 'battfake', changed reported battery charge level and verified that the LED patterns still work as expected. In addition, had debug code which printed to the console what the R, G, B duty cycle levels were for each transition and verified the expected values were achieved. Visually compared version with transitions to the previous version which changed abruptly.
