[edk2-platforms] [PATCH 04/11] MinPlatformPkg: Add BDS Board Boot Manager library

["Agyeman, Prince" <prince.agyeman@intel.com>]

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2336

As Minplatform's PlatformBootManager library instance implements
event signals (as specified in the minimum platform specification)
to trigger board actions, some of its functions namely
PlatformBootManagerWaitCallback and PlatformBootManagerUnableToBoot
will not have events signaled for boards to take action.

This library implements PlatformBootManagerWaitCallback
and PlatformBootManagerUnableToBoot which will be linked to Minplatform's
PlatformBootManager libary instance.

Added is an interface/header file that defines the board boot manager
library.

Also added is a NULL implementation of the board boot manager library
