Centralize port management state and use connectionId for device distinction #4699
Description
Context
As discussed in PR #4698 (#4698 (comment)), the current CapacitorSerial implementation uses a hardcoded "serial" path for all devices.
Proposed Solution
The intention is to use connectionId to distinguish between multiple connected devices. Port management states should be centralized to properly handle multiple devices.
