It's no change in application behavior to have these objects owned by
the function-scope static map in Protocol.cpp, while allowing us to
remove some ugly FIXMEs from time immemorial.
Now we will only load resources from $build/share/Lagom. On macOS, we
load from the bundle directory Contents/Resources instead. This
simplifies the commands and environment variables needed to execute
Ladybird from the build directory, and makes our install setup less
awkward for distributions and packagers.
Add a RequestServerService class that uses the LadybirdServiceBase class
added previously. Bind to it from the WebContentService's service_main()
during startup.
