i386: Add MAX_OPERAND_BUFFER_SIZE
When displaying operands, invalid opcodes may overflow operand buffer
due to additional styling characters. Each style is encoded with 3
bytes. Define MAX_OPERAND_BUFFER_SIZE for operand buffer size and
increase it from 100 bytes to 128 bytes to accommodate 9 sets of styles
in an operand.
