rust-components-swift includes all components in the same namespace

[tarikeshaq]

This is a follow up to #4815

With the v91.0.1 release of rust-components-swift all the component's swift code is released as one target. Meaning that name conflicts across components will fail to compile.

For now, that's okay, we don't have any name conflicts in the components we ship to iOS and focus. But, there are name conflicts in tabs and autofill. It's not a hard problem to workaround, we just rename whatever is conflicting, but we might want a better story for this
