classes/populate_sdk_ext: allow including toolchain in eSDK on install

If we're to completely replace the standard SDK with the extensible SDK,
we need to be able to provide the standard toolchain on install without
doing anything other than installing it, so that you can install the SDK
and then point your IDE at it. This is particularly applicable to the
minimal SDK which normally installs nothing by default.

NOTE: enabling this option currently adds ~280MB to the size of the
minimal eSDK installer. If we need to reduce this further we would have
to look at adjusting the dependencies and/or the sstate_depvalid()
function in sstate.bbclass which eliminates dependencies, or look at
reducing the size of the artifacts themselves.

Implements [YOCTO #9751].
