Brian Osman 4d3bfc511d Make all fragmentProcessors implicitly nullable in SkSL
This feature had devolved to just an assert, and one that isn't really
necessary - all of Ganesh is built to handle any child processor being
null. The next step is to remove nullable types entirely -- a large
amount of code.
