`WindowMethods` is used by the embedding layer to get information from the embedder. This change moves the functionality for getting screen size and `WebView` offsets to `WebViewDelegate`. This is important because `WebView`s might be on different screens or have different offsets on the screen itself, so it makes sense for this to be per-`WebView` and not global to the embedder. HiDPI and animation state functionality will move to the embedder in subsequent changes.

Please replace each `[ ]` by `[X]` when the step is complete, and replace `___` with appropriate data: --> - [x] `./mach build -d` does not report any errors - [x] `./mach test-tidy` does not report any errors - [x] These changes do not require tests because they just modify the `WebView` API surface a bit. <!-- Also, please make sure that "Allow edits from maintainers" checkbox is checked, so that we can help you if you get stuck somewhere along the way.--> <!-- Pull requests that do not address these steps are welcome, but they will require additional verification as part of the review process. --> Signed-off-by: Martin Robinson <mrobinson@igalia.com>
