MdeModulePkg: Sets the Cursor to selected BootOption.

Its been observed that in MenuManagerMenuApp when user
selects a different BootOption using Up/Down key, the
current Cursor position is not chaning.
Still points to the old BootOption.

This changes first dispalys/redraws the old BootOption
followed by new BootOption. Doing so will make current
cursor pointing to the user selected BootOption.
