From this is looks like timeouts are several times per day and on multiple platforms. I will mark it as flaky.

It's already marked as slow for debug, but even there it's timing out, at least twice on WebKit Win7 (dbg).

Mark touchpad-scroll-impl-to-main.html as flaky timeout

Marking it slow was not enough, it would still timeout on at least
WebKit Win7 (dbg).

Send GSB before switching to mainthread scrolling in smooth scroll path.

This cl is the equivalent of https://codereview.chromium.org/2854683002 fix for smooth scrolling
path,if the compositor handles the GSB and during the scrolling we have to switch to main thread
since the compositor cannot handle a GSU a GSB must be sent to the main thread since the original
GSB was handled on the compositor rather than being sent to the main thread.

touchpad-scroll-impl-to-main.html is the test that forces switch from compositor thread to main
thread in the middle of scrolling. It used to get executed with --disable-smooth-scrolling
in this cl I've moved the test to a new virtual test suite that has default scroll animation
value.

I have removed the test expectations since I have changed the test and this might fix the flake.

subpixel-accumulation.html needs scroll animation to be disabled and that's why I had to move it to
a new test suite.

Reland "Send GSB before switching to mainthread scrolling in smooth scroll path."

This reverts commit 0a6d89788324987fbad1450b2db6f113129a7130.

Reason for revert: touchpad-scroll-impl-to-main.html is a flaky test
that I changed it in the original cl and removed the tests expectations to see if the flake is fixed or not. Changing the test expectations caused unexpected test failure. In this reland I left the test expectations for touchpad-scroll-impl-to-main.html unchanged.

commit dfc61b12139e0a086e7e24994c7ef10a98b1aa2b

Reland "Send GSB before switching to mainthread scrolling in smooth scroll path."

This reverts commit 0a6d89788324987fbad1450b2db6f113129a7130.

Reason for revert: touchpad-scroll-impl-to-main.html is a flaky test
that I changed it in the original cl and removed the tests expectations to see if the flake is fixed or not. Changing the test expectations caused unexpected test failure. In this reland I left the test expectations for touchpad-scroll-impl-to-main.html unchanged.

Original change's description:
