UefiCpuPkg/Cpuid.h: Remove duplicated struct definition for leaf 1FH

Per SDM CPUID.0BH and CPUID.1FH outputs the same format of data in
EAX/EBX/ECX/EDX except CPUID.1FH reports more level types such as
module, tile, die.

The patch removes the unnecessary duplicated structure definitions
for CPUID.1FH because when the structure definitions for CPUID.0BH
can be used for CPUID.1FH.
