[PATCH v1] UefiCpuPkg/MpInitLib: Add missing explicit PcdLib dependency

["Wu, Hao A" <hao.a.wu@intel.com>]

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=2632

Both PEI and DXE instances of the MpInitLib are using PcdLib APIs, but
none of them list the dependency of the PcdLib in INF & header files.

This commit will explicitly add such dependency in .H and .INF files.

Test done:
Library level build pass for VS2015x86 tool chain
