UefiCpuPkg: Add dynamic type for PcdCpuMaxLogicalProcessorNumber
Currently, PcdCpuMaxLogicalProcessorNumber only supports fixed type. There are
some requests on this PCD to support dynamic type also. For example, platform
may dynamically set this PCD to actual processor count to save memory or improve
boot performance.
