Change the aspect ratio in normal mode

Browse Source 
Actual PC8801 series "high resolution" 24kHz CRT monitors display images with a maximum of 640x400 square dots, just like the PC9801 series.
The correct aspect ratio is 16:10, and the current 4:3 does not display images correctly in normal mode.
Change the definition of aspect ratio in PC8801.sv.

Note:
In 640x200 mode, the even lines in 400 line mode are simply hidden, so the aspect ratio remains the same.
