EmbeddedPkg/PrePiLib: Remove the performance measurements from the library

The PrePiLib should really be used for the PEI phase (not the SEC phase).
It is the DXE core that take the tick for the end of the PEI phase.

The Platform PrePi module should be responsible to take the tick when it
starts for the PEI phase.
