[roll] Roll fuchsia [ffx] Use concrete errors in emulator_instance

Migrate emulator_instance (specifically watcher.rs) from anyhow to
concrete error types. This improves error specificity and aligns with
the directive to use structured errors in libraries.

Updates callers in the emulator plugins (list, start, engines) to
handle the new error types, mapping them appropriately for the plugin
framework.
