[PATCH 1/4] MdeModulePkg/dec: Add PcdTestKeyUsed PCD.

[Jiewen Yao <jiewen.yao@intel.com>]

This PCD can be set by platform to indicate if there is any
test key used in current BIOS, such as recovery key,
or capsule update key.
Then the generic UI may consume this PCD to show warning information.

Other platform driver may also consume this PCD to know such info,
and report it via platform specific way.
