Yulong Wang 9a61388f0a [js/web] revise backend registration (#18715) ... ### Description This PR revises the backend registration. The following describes the expected behavior after this change: (**bolded are changed behavior**) - (ort.min.js - built without webgpu support) - loading: do not register 'webgpu' backend - creating session without EP list: use default EP list ['webnn', 'cpu', 'wasm'] - creating session with ['webgpu'] as EP list: should fail with backend not available - (ort.webgpu.min.js - built with webgpu support) - loading: **always register 'webgpu' backend** ( previous behavior: only register 'webgpu' backend when `navigator.gpu` is available) - creating session without EP list: use default EP list ['webgpu', 'webnn', 'cpu', 'wasm'] - when WebGPU is available (win): use WebGPU backend - when WebGPU is unavailable (android): **should fail backend init,** and try to use next backend in the list, 'webnn' (previous behavior: does not fail backend init, but fail in JSEP init, which was too late to switch to next backend) - creating session with ['webgpu'] as EP list - when WebGPU is available (win): use WebGPU backend - when WebGPU is unavailable (android): **should fail backend init, and because no more EP listed, fail. related PRs: #18190 #18144		2023-12-20 14:45:55 -08:00
