### Problem Description
<!-- Is your feature request related to a problem? Please add a clear and concise description of what the problem is. -->

BrowserWindow currently offers "moved" event related to moving a window, but it only has "will-resize" and "resize" events. I want to save the current dimensions of a window when its size changes, but "will-resize" and "resize" events get fired at every single pixel change. This results in an unnecessarily large number of saving function calls or a need for debouncing the event.

### Proposed Solution
<!-- Describe the solution you'd like in a clear and concise manner -->

Adding "resized" event to BrowserWindow will solve the problem stated above.

### Alternatives Considered
<!-- A clear and concise description of any alternative solutions or features you've considered. -->
