Compositor: Turn Color Balance options to inputs

Browse Source 
This patch turns the options of the Color Balance node into inputs.

In the process, each of the wheels were split into two inputs, a base
float and a color. For instance, Gain is controlled using both a Base
Gain and Color Gain, the former controls the gain for all channels while
the latter controls it per channel.

Reference #137223.
