Vlv2TbltDevicePkg/Override/GenericBdsLib:Remove useless Perf code

Our new performance infrastructure (edk2 trunk commit hash value:
SHA-1: 73fef64f14 ~
SHA-1: 115eae650b) can support to
dump performance date form ACPI table in OS. So we can remove
the old perf code to write performance data to OS.
