ManageabilityPkg/IpmiCommandLib:IPMI Command Library

BZ #: 4444

IpmiCommandLib is cloned from
edk2-platforms/Features/Intel/OutOfBandManagement/
IpmiFeaturePkg/Library/IpmiCommandLib in order to
consolidate edk2 system manageability support in
one place. Function header are added to the source
files and header files. Uncustify is applied to C
files and no functionalities are changed in this patch.

We will still keep the one under IpmiFeaturePkg/Library/
IpmiCommandLib until the reference to this instance are
removed from platforms.
