Revert 114898 - Add TabModalConfirmDialogDelegate to show simple tab-modal confirmation dialogs.

This CL carves a TabModalConfirmDialogDelegate class (modeled after ConfirmInfobarDelegate) out of RepostFormWarningController and makes it a subclass thereof.

It also removes the ShowRepostFormWarning method from BrowserWindow and its subclasses, in favor of a method in browser_dialogs.h.

BUG=92795
TEST=none
