storage: unify naming for drive protocol interface

Renamed `fDriveKind` to `fProtocol` across kernel storage subsystems
to clarify its purpose as a protocol identifier (e.g., "AHCI", "ATA-")
rather than a general "kind" classification.

Updated all affected header and source files:
- DriveMgr, HeFS, AHCI, ATADeviceInterface, and NeFS now consistently
  reference `fProtocol()` instead of `fDriveKind()`.
- Added streaming operators (`<<`, `>>`) to AHCI and ATA device
  interfaces for improved mountpoint interaction.
- Promoted `GetPortsImplemented()` and `SetPortsImplemented()` to
  public for AHCI device configuration.
- Added null checks and protocol verification logic in stream operators.

This refactor improves clarity and consistency when working with
storage devices across the kernel.
