DERBY-534: Support use of the WHEN clause in CREATE TRIGGER statements

Add the WHEN clause syntax to the grammar and wire it together with the
existing partial code for the WHEN clause.

Make RowTriggerExecutor and StatementTriggerExecutor execute the WHEN
clause and use the result to decide whether the trigger action should
be executed.

Add some basic positive tests for the currently supported subset of the
functionality.

> Support use of the WHEN clause in CREATE TRIGGER statements. The clause is described
in the SQL standard (2003) in chapter "11.39 <trigger definition>" under "<triggered
action>".
> There are traces in the code that suggests some work has been done on this earlier. If
anyone knows something about this, please add a comment to this issue.
