[roll] Roll fuchsia Revert "[lsc] Migrate all clients of fuchsia.sys2.ComponentResolver"

This reverts commit 28e39762b3aaec2c3d3bf4d1b29fbb87ca1e1848.

Reason for revert: b/227016951

Original change's description:
> [lsc] Migrate all clients of fuchsia.sys2.ComponentResolver
>
> This LSC migrates all usages of the `fuchsia.sys2.ComponentResolver`
> protocol to `fuchsia.component.resolution.Resolver`. The latter is in
> the SDK and the former will be removed after this CL. This was done
> in an LSC, instead of a soft transition for the following reasons:
>
> * All usages are in-tree, so we're confident that nothing will break.
> * The change is mechanical. That is, it only changes one namespace to
> another, and as such it's fair to assume that nothing will break.
> * A soft transition would have greatly slowed down the rollout
> of `fuchsia.component.resolution.Resolver`.
> * It would have been tricky to have `component_manager` support
> consuming both protocols at the same time.
