mb/google/rex: Allow to show early splash screen using GFX PEIM 

This patch chooses to show the early splash screen which is an
OEM feature. The current implementation is relying on the Intel
FSP GFX PEIM to perform the display initialization.

Having this feature allows the platform to show the user notification
with 500ms since boot compared to traditional scenarios where first
user notification is coming from kernel (typically ~3sec+ after cpu
reset). Eventually this feature will help to improve the user
experience while booting Intel SoC platform based chromeos devices.

BUG=b:284799726
TEST=Able to see the early splash screen on google/rex.
