[WebNN] Remove workarounds for TFLite backend (#23406)

The WebNN CPU device type may now target different backends, such as CoreML. Legacy special workarounds for the TFLite backend should be removed and allowed to fail as is, as these are implementation issues. Additionally, the WebNN EP should adhere to the WebNN API conformance. We assume all the WebNN ops should be supported, so remove the WebNN op support status for different device types in webnn-operators.md as well.

-[WebNN API](https://webmachinelearning.github.io/webnn) provides two device types `cpu` and `gpu` to leverage different on-device accelerators. WebNN API implementation in Chromium uses TFLite XNNPack delegate backend for `cpu` device type and DirectML backend for `gpu` device type. [The op support status](https://webmachinelearning.github.io/webnn-status/) behind these two backends is inconsistent.
+The [WebNN API](https://webmachinelearning.github.io/webnn) is available in the latest versions of Chrome and Edge on Windows,
+Linux, macOS, Android, and ChromeOS behind an <i>"Enables WebNN API"</i> flag. The operator support status may vary across these
+platforms. Check the [WebNN status](https://webmachinelearning.github.io/webnn-status/) for the latest implementation details.
