BZ:2583:
https://bugzilla.tianocore.org/show_bug.cgi?id=2583
Current DxeIpl has bindings for different processor
architectures, this results in MdeModulePkg has the
dependence with processor architecture packages such as
ArmPkg or RiscVPkg. This also leads CI testing to error
during package dependency check. Provide a default
DxeIplHandoff library to abstract processor
architecture from DxeIpl driver, platform can provide
its own library instance for the processor architecture-
specific implementation.
