SharedPartBuilder class Null safety

A Builder which generates content intended for part of files.

Generated files will be prefixed with a partId to ensure multiple SharedPartBuilders can produce non conflicting part of files. When the source_gen|combining_builder is applied to the primary input these snippets will be concatenated into the final .g.dart output.

This builder can be used when multiple generators may need to output to the same part file but PartBuilder can't be used because the generators are not all defined in the same location. As a convention most codegen which generates code should use this approach to get content into a .g.dart file instead of having individual outputs for each building package.
