WebUI TaskManager: Add method to set minimum window size on HTMLDialog.

Previously, the saved window size is used as the "minimum" size of window on HTMLDialog (cf. http://crbug.com/115403). This CL make the saved size as default size and adds the GetMinimumDialogSize() method in HTMLDialogUI to set minimum size of window separately.

This CL also enables the viwes::Widget::SaveWindowPlacement() on TaskManagerDialog by adding HtmlDialogView::GetWindowName() and HtmlDialogUIDelegate::GetDialogName() virtual functions. And this CL disables to save the window placement on TaskManagerDialog on views, since views::Widget has same feature which is enabled by this CL.

BUG=115403
TEST=manual on Windows, Linux with gtk and Linux with chromiumos=1
