[PATCH] IntelSiliconPkg/Library:Add BaseConfigBlockLib Library

[ethan.tsao@intel.com]

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=2318

Establish one copy of Config blocks library class and instance
in IntelSiliconPkg and remove copies from other silicon packages
, like KabyLakeSiliconPkg, CoffelakeSiliconPkg.
