Bug eclipse-lsp4j#494:

Remove dependency on xtext's @pure and ToStringBuilder

This commit removes @pure.  The next commit is going to remove
ToStringBuilder.

lsp4j.debug depends on xtext base at runtime, because the generated
POJOs import org.eclipse.xtext.xbase.lib.Pure and
org.eclipse.xtext.xbase.lib.util.ToStringBuilder. Neither @pure
nor ToStringBuilder are required by lsp4j.debug's functionality.
Removes the xtext dependency to shrink the set of lsp4j.debug's
dependencies.
