GS/HW: Try to keep old targets around without overlap or dirty areas

[refractionpcsx2]

Description of Changes

Try to avoid deleting targets which haven't been overlapped or dirtied.

Rationale behind Changes

Some games will preload some information then not touch it until after the game loads, but we eject things that haven't been used for 300ish frames, so sometimes this data can be ejected.

Same can happen for games if you spend too long in a pause screen/menu, causing the game to corrupt when you go back. An example of this may be using the shop in the Ratchet games, or changing the background in King's Field 4, then back again after waiting.

Suggested Testing Steps

Try games you think suffer from above, it might help.

Fixes #7332

Only way to make it happen again is switching from hw to sw render.

Okay I'm removing the test flag since this looks promising. I'll leave the other changes I made for now so we can see when it's working its magic

But still need tests for the following scenarios

ffx intro scene changes leave the old image untouched for a couple of frames
(Disgaea 2 fmv when booting the game through the BIOS)
Xenosaga 2 needs at least 240, else it flickers on scene transitions

Too bad it doesn't fix some games like Star Wars Ep3 but it does say something in the logs

Keep in mind this also happens on master, so no apparent changes happened.

The added reflections on Burnout Takedown cars vanish upon loading state or switching renderers.

[refractionpcsx2]

They will, nothing I can do about that.
