oniro-debug: create config files

Create bbclass files in meta-oniro-core that enable the user to activate the debug mode in local.conf.

Activating it is equivalent to build -dev images as of this commit.

Closes #599 (closed)

-# Extra image configuration defaults

-# The EXTRA_IMAGE_FEATURES variable allows extra packages to be added to the generated
-# images. Some of these options are added to certain image types automatically. The
-# variable can contain the following options:
-#  "dbg-pkgs"       - add -dbg packages for all installed packages
-#                     (adds symbol information for debugging/profiling)
-#  "src-pkgs"       - add -src packages for all installed packages
-#                     (adds source code for debugging)
-#  "dev-pkgs"       - add -dev packages for all installed packages
-#                     (useful if you want to develop against libs in the image)
-#  "ptest-pkgs"     - add -ptest packages for all ptest-enabled packages
-#                     (useful if you want to run the package test suites)
-#  "tools-sdk"      - add development tools (gcc, make, pkgconfig etc.)
-#  "tools-debug"    - add debugging tools (gdb, strace)
-#  "eclipse-debug"  - add Eclipse remote debugging support
-#  "tools-profile"  - add profiling tools (oprofile, lttng, valgrind)
-#  "tools-testapps" - add useful testing tools (ts_print, aplay, arecord etc.)
-#  "debug-tweaks"   - make an image suitable for development
-#                     e.g. ssh root access has a blank password
-# There are other application targets that can be used here too, see
-# meta/classes/image.bbclass and meta/classes/core-image.bbclass for more details.
-# We default to enabling the debugging tweaks.
