Rascal support for working with error trees

[PieterOlivier]

This PR contains the interpreter implementation of most of the conclusions Rascal Amendment Proposal #16: Support for error trees in Rascal
The only exception is that error tree support for "indexed field assignment" is not implemented as regular indexed field assignment is not implemented in the interpreter anyway.

Parse error recovery was added to Rascal in PR #2038.
When parsing with allowRecovery=true, the resulting parse trees can contain error and skipped nodes.

Working with error trees at the appl/prod level is possible but cumbersome. This tracking PR will add better support for working with these trees.

The following pull requests contribute to this one:

• Tests for error tree semantics in Rascal #2246 Implements a set of tests for envisioned semantics of error trees in Rascal
• Implemented low-hanging fruit from error tree support #2309 Several fixes to implement error tree semantics for the easier cases (low hanging fruit)
• Deep match amb child memoization #2310
• Memoization of amb nodes in visit #2316
