Promote the uneven-4-way partition disable to speed 1

[chengchen-google]

The speed feature was enabled at speed 2.
It turns out that its performance at speeed 1 is also good.

On speed 1, RA, the tradeoff is:

Testset PSNR-YUV EncSpeedUp Ratio
A1 (17 frames) 0.03% 6.23% 207.7
A2 (33 frames) 0.06% 6.70% 111.7

What is the anchor @chengchen-google for these results?
I saw a bigger loss on commit 2abcfff:

• 0.13% average loss w/o B2
• 0.06% on A1
• 0.08% on A2
• 0.19% on B1
• 0.19% on A3
• 0.34% on A4
• Neutralish on A5 but most clips have a loss

If you see something similar, I'd suggest disabling based on resolution (1080+) and also keeping it on for screen content perhaps?

The anchor is 5d628d8.
I haven't tested for other resolutions. I do have an impression that the performance change on lower resolutions is larger. Do you think we need the full information to make a decision? If other resolution shows larger loss, perhaps we can make this speed feature dependent on resolution?

Yes, pls run other resolutions (RA 33 frames) and let's make a decision based on the result -- resolution dependent was indeed my suggestion.
