Refactor BasePagedList<T> and remove PagedListMetaData

BasePagedList<T> no longer inherits from PagedListMetaData and now directly implements IPagedList<T>. Added properties (PageCount, TotalItemCount, PageNumber, PageSize, HasPreviousPage, HasNextPage, IsFirstPage, IsLastPage) with protected set accessors to BasePagedList<T>. Removed PagedListMetaData class. Added Subset list of type T to BasePagedList<T> and initialized it as an empty list.
