[OE-core] [PATCH 2/2] bitbake.conf: Define source package, disabled by default

[Haris Okanovic]

Add ${PN}-src to PACKAGES with a default set of FILES_{PV}-src
per FHS:
https://refspecs.linuxfoundation.org/FHS_3.0/fhs-3.0.html#usrsrcSourceCode

Define a staging directory SRC_D under ${D}.

Define ENABLE_SRC_INSTALL to enable source staging via package.bbclass's
do_install_source() task. It's disabled by default, but may be
overridden by distro configs or individual recipes as needed.

This is change is part of a series which add source packages to OE.
