ShellPkg/DpDynamicCommand: Add ResetEnd support in DP command

DP command should be able to parse the FPDT ACPI table and dump
the ResetEnd which was logged at the beginning of the firmware
image execution. So that DP can calculate SEC phase time duration
start from the beginning of firmware image execution.
