Implement intersect with prefix pattern for PartialPath and PathPatternTree

[Cpaulyz]

Description

To support authorization, this PR implements two algorithms about intersection.

• PartialPath

  /**
   * Generate a list of partial paths which are the intersection of this path pattern and input
   * prefix pattern.
   *
   * @param prefixPattern must be a prefix full path ending with one "**", like "root.sg.**"
   * @return a list of partial paths which are the intersection of this path pattern and input
   *     prefix pattern.
   */
  public List<PartialPath> intersectWithPrefixPattern(PartialPath prefixPattern);

• PathPatternTree

  /**
   * Intersect the pattern tree with the full path prefix tree, and return the intersected pattern
   * tree.
   *
   * @param patternTree any pattern tree
   * @param fullPathPrefixTree the included pattern must be fullPath or prefix pattern(e.g.
   *     root.sg.**)
   * @return the intersected pattern tree
   */
  public static PathPatternTree intersectWithFullPathPrefixTree(PathPatternTree patternTree, PathPatternTree fullPathPrefixTree);
