libservo: Make Servo (and servoshell) more resilient against extreme sizes (#39204) 
Make several changes which should address panics and inconsistent
behavior around attempts to set extreme sizes:

1. Limit the minimum size of the `RenderingContext` to 1 pixel by 1
   pixel. This should address problems where users of the API try to
   directly set the size to a zero or negative dimension. In addition,
   improve the documentation around `WebView::resize` to mention this.
2. Clamp values sent in the `WebViewDelegate::request_resize_to` method
   to be at least 1x1. This prevents Servo from sending nonsense values
   to embedders. Improve documentation in this method.
3. In servoshell:
    - More consistently clamp inner and outer window size values.
    - Clamp all resize values to the available screen size, so that
      large screen sizes aren't processed directly.

Testing: This change fixes an existing WPT and adds two new API tests.
Fixes: #36763.
Fixes: #36841.
Fixes: #39141.
