Changes to all parts of the project:

• Removed a redundant macro (HPIO_NORMALIZE_PTR)
• Deleted XTIDE_Universal_BIOS/Inc/BiosData.inc since that was also redundant.
• Size optimization: Changed the LOAD_BDA_SEGMENT_TO macro to use the stack on 186+ processors (the old behaviour can still be used where needed).
• Made other minor size optimizations and cleanups to various functions, mostly in the Int13h handler.
