This introduces a new PCD 'PcdPciResAllocTableBase' to allow a platform
to provide its specific PCI resource allocation pool at runtime.
PCI Enumerator will allocate required resources in the range.
If the PCD is not provided, a default range will be used.

This will create a HOB for PCI Root Bridge Resource information.
The PciRootBridgeInfo Hob can be used to update resource ranges of multiple
root bridges in platform PCI tree ASL.
A payload can also use this info to skip duplicated root bridge scan.

PciEnumeration() scans a single PCI root bridge currently.
The PCI_ENUM_POLICY_INFO structure will be generated at build time,
and this will allow PCI enumeration more flexible.
typedef struct {
UINT8 DowngradeIo32;// default:1
UINT8 DowngradeMem64; // default:1
UINT8 DowngradePMem64;// default:1
UINT8 Reserved;
UINT8 BusScanType; // default:0 (0: list, 1: range)
UINT8 NumOfBus; // the number of BusScanItems
UINT8 BusScanItems[0];
} PCI_ENUM_POLICY_INFO;

This provides basic insertion sort API for Linked List. As part of change,
this insertion sort is used for PCI BAR calculation by its alignment
and for shell commands list by its name.
