Prepares the removal of the final annotation (Tree@\loc), including its definition and all of its uses.

[jurgenvinju]

This PR implements the first step in a bootstrap cycle to replace Tree@\loc by loc Tree.src

1. The refactorig is automated fully by lang::rascal::upgrade::UpgradeAnnotationsToKeywordParameters
2. Used report from this module first to see what the relevance and impact would be
3. No manual changes were necessary but some additional documentation (deprecation) lines were added as by-catch.
4. The standard library in particular the ParseTree module is not binary compatible to its previous version. So this must be a "major" version bump and a big bang release for all libraries.
5. This change requires thoughtful revising of the documentation in the website project, including the reference manual and recipes. For a separate PR.

This change impacts all projects with code that uses Tree.\@loc; so that's a lot. The first of the typepal project on which the Compiler and the checker on the current project depend. Releasing a refactored version of typepal is the next step.

This branch does not remove the old feature yet for two reasons:

1. that would break the code that has not migrated yet. However, the refactoring will change the exceptional behavior for a missing .src field. From now on it will produce the default instead of throwing NoSuchAnnotation!
2. at least the synax definition is still required to be able to execute the refactoring.

Commits:

• borrowed upgrade folder from no-more-annotations branch to reuse refactoring code
• ran update function on Assignment test module
• rewrote the annotation tests using the update refactoring
• automatically refactored all declarations and uses of annotations
• folded src kw parameter into the primary definition of Tree

[jurgenvinju]

The update functionality that refactors uses of annotation syntax to keyword parameter syntax is a candidate for inclusion in the Rascal LSP server:

• as a lense
• as a refactoring?

It has to run on the entire project to make sense as the refactoring is "dumb"; it does not follow name resolution links it just replaces all syntactical constructs in a consistent manner.
