XDS Debugging: Rename of files and update devguides-book.yml

The debugging section for XDS needs new file names and also
needs to fix the order in which the files appear as topics.
I have done both.

+# Debug your first AGL application
+
+Debug is based on gdb and you need to use `xds-gdb` as a wrapper on gdb to
+cross-debug your application.
+
+This tool allows you to debug an application built with XDS without the need to install gdb or any cross tools.
+
+Two debugging models are supported:
+
+1. native debugging
+1. XDS remote debugging requiring an XDS agent/server setup and that allows you to cross debug your application.
+
+By default XDS debug model is used and you need to define `XDS_NATIVE_GDB`
+variable to use native gdb debug mode instead.
