UefiCpuPkg/CpuDxe: change level of DEBUG message 

BZ#1127: https://bugzilla.tianocore.org/show_bug.cgi?id=1127

It's reported the debug message in CpuDxe driver is quite annoying in
boot and shell, and slow down the boot process. To solve this issue,
this patch changes the DEBUG_INFO to DEBUG_VERBOSE. On a typical Intel
real platform, at least 16s boot time can be saved.
