Subject: UefiPayloadPkg: Fix boot shell issue for universal UEFI payload

After moving BDS driver to a new FV for universal UEFI payload,
the shell boot option path is not correct since it used the BDS
FV instead of DXE FV in its device path.
This patch would find the correct FV by reading shell file.
It also removed PcdShellFile by using gUefiShellFileGuid.
