Ladybird/WebView: Search for resources using installed location

Browse source 
Reorganize the logic for initializing s_serenity_resource_root.

Now, we initialize it in platform_init(), and move platform_init to the
top of initialize_web_engine.

Add a branch at the end of the function to check
``QApplication::applicationDirPath()`` for the location of the
executable, and base the location of resources on that.
In an installed configuration, this will be /some/path/bin, with the
resource root set to /some/path/share/, looking for files in
/some/path/share/res/resource-type.

This matches up with some upcoming CMake changes to install resources in
CMAKE_INSTALL_DATADIR.
