Add native pixel ratio 640:448 (10:7)

Description of Changes

Add native pixel ratio 640:448 (10:7) for some games.

Rationale behind Changes

Most games have an internal native pixel ratio of 640:448 (10:7), which is then stretched to 4:3, and the developers at the time were also well aware of this. So 4:3 usually gets the correct ratio. However, there are always exceptions, and some game developers seem to insist on using the original pixel ratio instead of 4:3 to express the true effect of the game. If still stretch it to 4:3 in pcsx2, causing the y-axis to be stretched by 7.14% and the character to look a bit thin and long visually.

For example:

Tekken Tag Tournament

Sengoku Basara X

Tenchu: Fatal Shadows
Although its internal resolution is 512:448, it seems to follow the 10:7 ratio.

Are you able to squash the commits down into one and prefix it?

Sorry, I'm not very experienced in this.
Do I need to delete these commits and pr it again?

[F0bes]

I took care of it.

You would interactive rebase and mark all of the commits after the first one as squash. Once you finished you would force push back to your branch.

Code looks fine, haven't tested it.

[Berylskid]

Tested some games with pnach code that includes gsaspectratio=10:7, and all of them worked flawlessly.

Are you adding these to GameDB? Midnight Club - Street Racing (atleast the NTSC release) has the same "quirk".
works fine on it

I just checked the game and you are right. It is obvious in the joy settings screen.

4:3 ratio

native ratio

I usually think that only designers from Japanese companies, especially when porting games from traditional arcades, would keep the 10:7 native ratio.It's hard to imagine a company like Rockstar doing this.

[the-burrito-triangle]

I think many Japanese game developers were confused as to what aspect ratio should be used. For example: FF X draws squares and ovals with 4:3 or rectangles and circles with the new 10:7 option. Clearly, not everyone agreed on the same aspect ratio when developing this game.

Anyways, the new 10:7 aspect ratio seems to work fine for me so far. Thanks for adding it.
