[PATCH V4 1/2] MdeModulePkg: Add a pcd to set the OS indications bit

["Gao, Zhichao" <zhichao.gao@intel.com>]

From: Bret Barkelew <Bret.Barkelew@microsoft.com>

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1678

Add a pcd PcdPlatformRecoverySupport to conditionally
set an OS indications bit and set the 'PlatformRecovery####'
variable. This pcd would also control whether the BDS
support platform recovery or not.
Update the uni file for description of the pcd.
