[meta-arago,scarthgap] packagegroup-arago-tisdk-graphics: add mesa-demos and sdl2

From: Randolph Sapp <rs@ti.com>

Add the new mesa-demos package to this group so that users and scripts
can use eglinfo to query information about supported extensions and
configs for multiple platforms. It also adds vkgears and es2gears to
test Vulkan and GLES 2 respectively.

Add libsdl2 as it's a useful, minimal graphics toolkit that allows users
to build GLES and Vulkan applications with less boilerplate. We have a
few internal test applications that currently use it.

Any reason these applications could not be added here? libsdl2 like other
pure libraries should only be added as dependencies of the applications
that use them.

While I normally agree with this sentiment, there are currently private test
applications that depend on SDL2. I can tack this directly into the test groups
if that's preferable. There was just some talk about introducing it as customers
who don't want the overhead of Qt may find it preferable to raw EGL+GLES.

So... there is a non-public program that we download during testing that 
requires the library to be on the system in order to run?  And this 
program cannot be made available...

In general I agree with Andrew on this.  We should not be randomly 
including libraries in the rootfs that do not have programs that require 
them.

It might better to create a new packagegroup for running these kinds of 
tests and then the test can pull that packagegroup 
(packagegroup-arago-tisdk-graphics-testlibs?) as part of the test.  That 
way we keep the base rootfs cleaner for everyone else *not* running this 
private hidden mystery program.  We can build that packagegroup as part 
of ti-world so that is available in the package feed.
