Reorganize tests for samples so the test is discoverable from the sample

Reorganize tests for samples so the test is discoverable from the sample

This change gets rid of the legacy "samples/test/samples/samples.status" folder structure. Instead it moves to "samples/samples.status", and each sample's test moves into its "test" folder.

The benefit is less "..", easier to find the test for the sample, matching the structure of "pkg" and reducing levels of nesting. My other motivation is to help fix https://code.google.com/p/dart/issues/detail?id=12865, and generally make it easier to write tests for the web samples.

Hi Devon & Siggi,

I don't know that we have an owner for samples tests, but since you guys wrote
most of them I figured you'd be the right people to send this CL to :)

What do you think about this cleanup?
Thanks! -John

File samples/samples.status (right):

https://codereview.chromium.org/23717003/diff/1/samples/samples.status#newcode7
samples/samples.status:7: [ $browser ]
hmmm, the diff tool isn't helping things here. but you can compare against:
https://codereview.chromium.org/23717003/diff/1/samples/tests/samples/samples...

No actual statuses should have changed.
