[PATCH 2/3] MdeModulePkg/Logo: Add a PCD to control the position of the Logo

["Sean Rhodes" <sean@starlabs.systems>]

When set to true, the Logo is positioned according to the BGRT
specification, 38.2% from the top of the screen. When set to false,
no behaviour is changed and the logo is positioned centrally.
