Refactored BootKit and DiskImage framework, minor kernel fixes

- Refactored BootKit classes:
  - Renamed `BTextWriter` → `BootTextWriter`
  - Renamed `BFileReader` → `BootFileReader`
  - Improved consistency across `BootKit.h`, `BootThread.cc`, and related files.

- Updated NetBoot module:
  - Standardized text writer usage.
  - Improved error handling for missing patches and EEPROM flash.

- DiskImage framework improvements:
  - Introduced `DI_DISK_IMAGE` struct.
  - Added new `DIFormatDisk()` and `DIFormatNeFS()` functions.
  - Improved error handling and structure alignment.

- Kernel enhancements:
  - Updated PE loader structures for better readability.
  - Renamed PE header fields for consistency.
  - Improved SwapDisk API structure (`SwapDiskHdr` → `SWAP_DISK_HEADER`).
