macros: Replace macro invocations with expanded nodes
Different parsing functions need to be called based on the context
surrounding the macro invocation. This commit adds a flowchart trying to
explain the base resolving rules
Macro expansion happens at the same level as stripping, where nodes
might get removed if they are gated behind an unmet predicate. We also
perform macro expansion during this visitor's pass.
What we can do is thus to replace macro invocations with new items that
might have resulted from macro expansion: Since we're already mutating
numerous elements by removing them if they should be stripped, we can
also add elements if they should be expanded.
This commit also "fixes" macro test cases so that they are now accepted
by the new parser, which is more strict than it should for now.
