Xcode: Remove the top-level Sources and Resources groups

This addresses duplicate file reference warnings from xcodebuild caused
by the same file reference being a member of both the target's group and
the top-level Resources group. Since resources are already a member of
their associated target's group the top-level Resources group isn't
strictly necessary, and removing it results in a project structure
closer to that of a current Xcode project template.

Fixes: #15272
