Subject: [PATCH] Update webidl files for TextEncoder and TextDecoder (#37952)

This PR updates the webidl files for `TextEncoder` and `TextDecoder`.
For `TextDecoder.webidl`, the type `AllowSharedBufferSource`, as defined
in the latest spec, is replaced with `BufferSource` as servo currently
does not support `ShareArrayBuffer`

Testing: This update does not introduce any change to the generated rust
binding, so the existing testing would suffice
