In BrowserElementChildPreload.js and BrowserElementParent.js, we add code to support 'copypaste-docommand' and 'do-command' to handle to copy/paste/cut operation from text_selection_dialog.js in Gaia. We need to clean it up since SelectionCarets and text_selection_dialog.js are removed in bug 1221459 and bug 1221462. Also the test case at [1] might need to be revised.

Thank you for the review! That's why wee need to delete the obsolete code to avoid confusion :)
