As previously discussed in #38229. To recap: `badcert.jpg` was made
unused in 8422dac811 and `tumbeast.png`
and its associated file of `not-found.html` were superseded at some
point by a message in `neterror.html` (if it were still used, it'd
surely be
[embedded](https://github.com/servo/servo/blob/main/components/shared/embedder/resources.rs).)
This PR also removes two unnecessary spaces inside of the new tab's CSS
file, ensuring a consistent 2 space indentation in the file and saving 2
bytes.
Testing: Unnecessary, as this commit only removes unused assets (and
fixes one style nit).

This implements a simple tab system for servoshell:
- The egui part uses the built-in SelectableLabels components and
display the full tab title on hover.
- WebView structs now hold all the state for each WebView. When we
need "global" state, we return the focused WebView state, eg.
for the load status since it's still global in the UI.
- New keyboard shortcut: [Cmd-or-Ctrl]+[W] to close the current tab.
- New keyboard shortcut: [Cmd-or-Ctrl]+[T] to create a new tab.
- The new tab content is loaded from the 'servo:newtab' url using a
couple of custom protocol handlers.
