MdeModulePkg: Change BootLogoEnableLogo use INTN for minus value
The parameter name is also changed from Coordinate* to Offset* to
reflect that it's the offset to the location specified by Attribute.
For example, when the Attribute is Center, OffsetX and OffsetY are
used to specify the offset to the Center. OffsetX = 100 means
100 pixels right to the Center.
(Sync patch r18867 from main trunk.)
