Bug 546219: [Commonmark] Rework source blocks

  - Rename *BlockItem to *BlockNode in accordance to common AST
    terminology and for better distinction of list item
  - Rename SourceBlock to SourceBlockType to reflect its function
  - Improve SourceBlockBuilder to provide access to more information,
    especially when parsing nested nodes
