fwmanager: Strengthen BootControl error contract

Tighten BootControl::Error from Debug-only to
`core::error::Error + system_control::Error` so the orchestrator gets
Display and a source() cause chain instead of just the Debug dump, and
so generic `BootControl` consumers can categorize failures via kind()
without downcasting to a concrete error type.

HAL reset controllers keep the existing Error/kind() pattern unchanged;
the new BootError adapter supplies the core::error::Error machinery over
any HAL error, so no per-implementation work is required.

Cover the combined bound with a compile-time fence and tests for Display
output, source(), dyn downcast, and kind() reached through a generic
BootControl.
