Automatically format GN build files under the components directory

This submission primarily involves automatic formatting of GN build files (BUILD.gn) in certain subdirectories under the //components/ directory that start with [p-z]. Specific operations include: using the "gn format" tool for unified formatting, shortening target references (such as removing the :target suffix), deleting duplicate dependencies, and allowing the GN tool to automatically correct formatting irregularities. This change does not involve any C++/Objective-C source code or business logic, and is solely an optimization of the build configuration file formatting.
