CSSPaint: Move layout tests in csspaint/ to http/tests/csspaint/

third_party/WebKit/LayoutTests/csspaint/resources/test-runner-geometry-logging.js

-// Test runner for the paint worklet.
-//
-// Calls a given function with a newly created element, and prints the expected
-// geometry to the console.
-//
-// Runs each test sequentially after a layout and a paint.
-//
-// Usage:
-// testRunnerGeometryLogging([{
-//      func: function(el) {
-//          el.style.width = '100px';
-//          el.style.height = '100px';
-//      },
-//      expected: {width: 100, height: 100},
-// ]);
