fix: Dispose codec after completing frame creation (#159945)
ref https://github.com/flutter/flutter/issues/93404,
[comment](https://github.com/flutter/flutter/issues/93404#issuecomment-2525453113)
and
[comment](https://github.com/flutter/flutter/issues/93404#issuecomment-2547622795).

Added a process to call `ui.Codec`'s `dispose`.
With this change,
[HtmlBlobCodec](8e0993eda8/engine/src/flutter/lib/web_ui/lib/src/engine/html_image_element_codec.dart (L100))'s
dispose will be called in Safari when using CanvasKit, and
`revokeObjectURL` will be executed as expected.

If this fix looks good, I will open the
https://github.com/flutter/flutter/pull/161481 to remove the
`AlearmClock` from the `BrowserImageDecoder`.
