Fixed MUL instruction tests with SIB byte encoding. When using SIB byte with Base=101 (EBP) and Mod=00, it requires a 32-bit displacement. Replaced incorrect encodings with proper ones for [eax] and direct memory addressing.

Fixed special case in MOV tests with EBP addressing. When Mod=00 and R/M=101 (EBP), it indicates a 32-bit displacement-only addressing mode, not [EBP]. Added correct test cases with Mod=01 and zero displacement.
