fb4720d3 - [BuilderTransform] Replace use of TypeExpr with a special $builderSelf variable

[BuilderTransform] Replace use of TypeExpr with a special $builderSelf variable For all of the `build*` calls, let's use a special variable declaration `$builderSelf` which refers to a type of the builder used. This allows us to remove hacks related to use of `TypeExpr`. Reference to `$builderSelf` is replaced with `TypeExpr` during solution application when the builder type is completely resolved.
