elm perf tool - bring one back to efl

expedite is basically dead. because it's out of tree and because it
was ported to eo too early... but it's also not a great tool given it
requires manual addition of engines and can't test elm stuff (complex
widgets).

so this is an elm based performance tool. i've added some tests (taken
from expedite and modified a bit). to get the ball rolling. the idea
is to add all the important core tests (rects, images, text, video
etc.) and then add widget/smart object like tests that go beyond what
expedite did. the problem with these tests is they are dependent on
theme. there isn't really any way around that... but i might
categorize tests in the end.
