QuarkPlatformPkg/ForceRecovery: Add UEFI application to force recovery 

https://bugzilla.tianocore.org/show_bug.cgi?id=138

This UEFI Application sets a sticky bit that persists across reset
to force a boot mode of BOOT_IN_RECOVERY_MODE.  It then performs
a warm reset using the UEFI Runtime Service ResetSystem().
