[PATCH 00/14] Introduce PlatformInitLib in OvmfPkg

["Min Xu" <min.m.xu@intel.com>]

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3863

There are 3 variants of PlatformPei in OvmfPkg:
 - OvmfPkg/PlatformPei
 - OvmfPkg/Bhyve/PlatformPei
 - OvmfPkg/XenPlatformPei

A lot of common code can be shared in above PlatformPeis. Further more,
with the upstreaming of TDVF (Pei-less boot mode), a library which
wraps the common functions is needed. PlatformInitLib is designed
to meet this requirement.

PlatformInitLib is designed to run in both PEI and SEC. So global
variables and dynamic PCDs are avoided.

As the first stage, OvmfPkg/PlatformPei will be refactored with
PlatformInitLib. In the future we will refactor other PlatformPeis
with this lib as well.

Patch 1 - 2: 
Create initial version of PlatformInitLib and move Cmos / Hob functions
to the lib.

Patch 3:
Move global variables in PlatformPei to PlatformInfoHob. Changes are
all in OvmfPkg/PlatformPei.

Patch 4 - 12:
These patches restruct the functions which set PCDs into two, one for
PlatformInitLib, one for PlatformPei.

Patch 13 - 14:
Pure move from PlatformPei to PlatformInitLib.
