Vlv2TbltDevicePkg/PlatformPei: Add boot mode detection

Add boot mode detection back into PlatformPei that was
inadvertently removed in the following commit:

https://github.com/tianocore/edk2-platforms/commit/d6211390793fbd0a89b14001c43e0ef942c85425

Boot mode detection at this point is required to detect
the boot mode of BOOT_ON_FLASH_UPDATE that is required
to detect, coalesce, and process UEFI Capsules.
