[PATCH for-edk2-stable201905] Revert "EmulatorPkg: don't display the cpu current speed"

["Laszlo Ersek" <lersek@redhat.com>]

This reverts commit 7cea4d71a8a87a93924a07ab32348332f5881ef9.

Said commit was not suitable for pushing during the edk2-stable201905 hard
feature freeze; it was pushed only by mistake. The subject line referenced
EmulatorPkg, but the patch changed MdeModulePkg/UiApp, regressing the
display of the CPU speed from SMBIOS in multiple platforms.
