Change the representation of ShadowRoot nodes in render tree dumps

[Kent Tamura]

We had better show ShadowRoot nodes explicitly in render tree dumps instead of showing #document-fragment.

Example:
Editing range dump:
-EDITING DELEGATE: shouldChangeSelectedDOMRange:(null) toDOMRange:range from 0 of DIV > #document-fragment to 0 of DIV > #document-fragment affinity:NSSelectionAffinityDownstream stillSelecting:FALSE
+EDITING DELEGATE: shouldChangeSelectedDOMRange:(null) toDOMRange:range from 0 of DIV > #shadow-root to 0 of DIV > #shadow-root affinity:NSSelectionAffinityDownstream stillSelecting:FALSE

Caret dump:
-caret: position 0 of child 0 {DIV} of child 0 {#document-fragment} of child 1 {INPUT} of child 3 {DIV} of body
+caret: position 0 of child 0 {DIV} of {#shadow-root} of child 1 {INPUT} of child 3 {DIV} of body

Selection dump:
-selection start: position 0 of child 0 {#text} of child 0 {DIV} of child 0 {#document-fragment} of child 3 {INPUT} of child 1 {P} of body
-selection end:   position 15 of child 0 {#text} of child 0 {DIV} of child 0 {#document-fragment} of child 3 {INPUT} of child 1 {P} of body
+selection start: position 0 of child 0 {#text} of child 0 {DIV} of {#shadow-root} of child 3 {INPUT} of child 1 {P} of body
+selection end:   position 15 of child 0 {#text} of child 0 {DIV} of {#shadow-root} of child 3 {INPUT} of child 1 {P} of body
