android_system_image module type is a specialization of the android_filesystem module type. Currently, it adds a build rule for creating linker.config.pb from the information about all the other files in the filesystem and includes linker.config.pb to the filesystem as well. To do so, the filesystem module now provides a function pointer which subtype modules like android_system_image can implement to pass extra files that they want to package in the filesystem. In addition, the linkerconfig package is revised to make it possible to build linker.config.pb file outside of the package. Bug: 185391776 Test: m microdroid and inspect etc/linker.config.pb in it.
