[meta-arago][master][discussion] Qt package groups and config locations

[Randolph Sapp <rs@ti.com>]

Hey,

Asking for some general advice before I submit the next series. Cleaning up
meta-qt* package groups and everything there is a bit of a logistical argument
to be made.

We now have an official requirement tracking Qt6 enablement which means more
automated testing. At the same time I do not think meta-arago should be
inherently dependent on a layer as heavy as meta-qt*. I'm planning on making a
series of isolated package groups and configs that can be toggled through a
distro feature.

Where do we think this should belong? The distro layer or the extras layer? I'm
leaning toward the distro layer as these are ultimately distro specific configs,
but I can understand that some may believe this is inherently "extra" content.
Regardless, the test layer will need to be updated to point to this.

Maybe it should be a generic "software" layer? I don't like splitting things
unnecessarily, but this is a weird example where we need certain features
enabled for both testing and release, but it doesn't really make sense to
duplicate it. No clue. Any opinions?

Regards,
Randolph
