[PATCH 1/3] MdeModulePkg/dec: Add PcdRecoveryFileName PCD.

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

This PCD is used to indicated the recovery file name.
The previous name - FvMain.Fv is hardcoded in FatPei and CdExpressPei.
It does not make sense to force the name.

Now a platform may use any recovery file name.
