docs/manual: add the virtual packages list
Add the list of virtual packages as an appendix to the manual. Also reference this list from appropriate locations elsewhere in the manual: - in section 7.2.2. "Config.in file", after the existing explanations on dependencies on target and toolchain options, on a linux kernel, and on udev /dev management, - in section 7.2.10. "Infrastructure for virtual packages", in the provider Config.in and .mk explanations, to have the list of existing symbols to select (in Config.in) and packages to provide (in .mk).
