Description: http/tests/webgpu/webgpu/shader/execution/expression/call/builtin/bitcast.html This test has been a consistent timeout since Sequoia. Interestingly looking at the flakiness dashboard the first consistent timeout appears at 294307@main. This commit [WebGPU] Enable CTS in Debug and skips a bunch of similiar tests. This issue can be reproduced using command: run-webkit-tests --no-build --no-retry --no-show-results --exit-after-n-failures=1 --expect-pass --iterations=1000 --force --debug http/tests/webgpu/webgpu/shader/execution/expression/call/builtin/bitcast.html History: https://results.webkit.org/?suite=layout-tests&test=http%2Ftests%2Fwebgpu%2Fwebgpu%2Fshader%2Fexecution%2Fexpression%2Fcall%2Fbuiltin%2Fbitcast.html&style=debug&model=Macmini9%2C1&recent=false Test Run: https://build.webkit.org/#/builders/1701/builds/803

We can either skip this test in Debug or increase the timeout on it
