Upstream shapedetection tests to WPT Moved shapedetection tests under third_party/blink/web_tests/shapedetection/, third_party/blink/web_tests/fast/shapedetection/, third_party/blink/web_tests/http/tests/shapedetection/, to third_party/blink/web_tests/external/wpt/shape-detection/, excludes the Text detection part as which is still a sister informative specification of Shape Detection. Copyed third_party/blink/web_tests/shapedetection/resources/big-buffer-helpers.js to wpt/shape-detection/resources/shapedetection-helpers.js and extended it by adding a wrapper promise test, detection_test. Moved third_party/blink/web_tests/shapedetection/resources/mock-barcodedetection.js and third_party/blink/web_tests/shapedetection/resources/mock-facedetection.js to wpt/resources/chromium/ Used the testharness from wpt/ and rewrited tests to remove use of generate_tests as which is discouraged in wpt. Rewrite detection-on-worker.html as detection-on-worker.worker.js by using wpt preferred worker test framework. Rename detection-support.html as detection-getSupportedFormats.html as *-support.html is treated as support file rather than test file in wpt. No new tests have been added.
