Promote tx stat pruning to Speed 3
The speed feature was at speed 4.

Enabling the speed feature at speed 3 shows
encoder speed up with acceptable coding loss.

New test on top of base commit 5d628d8

Speed 3
Testset PSNR-YUV EncSpeedUp Ratio
A1 (17 frames) 0.14% 8.28% 59.1
A2 (33 frames) 0.17% 6.53% 38.4

Original test on top of base commit fe1bfde

Performance on RA speed 3
Testset PSNR-YUV EncSpeedUp
A1 (17 frames) 0.15% 6.55%
A2 (33 frames) 0.22% 5.68%

Besides, we tested the speed feature at speed 2, it does not
meet the bar for A1.

Performance on RA speed 2
Testset PSNR-YUV EncSpeedUp
A1 (17 frames) 0.16% 4.02%
A2 (33 frames) 0.13% 4.46%

The trade off for speed 2 A1 is less than the threshold, so suggest to move it up to speed 3 instead of 2. In addition, as the trade off for speed 3 with class A2 just pass the threshold, it would be better to check the performance with av2-enc ToT. If it's still passing 25 threshold, we can turn it on for speed 3.

Thanks for the review. I agree with only turning it on for speed 3. I will update the PR.
