fix sliverfixedextent with sliverchildbuilderdelegate does not correct calculate max scroll extent (#39142)

One of our linux/android Moto G4 has alerts (emergency, amber, etc.)
turned on. That's probably the cause of the flakiness. I've turned it
off.

Let's mark this as non-flaky and see if it's fixed. If not, I'll move it
to mac/android and see if that fixes the flakiness.

I think the most important thing to do right now is to mark it as
non-flaky so those who really break the test could get a notification.

This changes the behavior of text fields, Material buttons, and Chips so that if they are disabled they lose focus. Before this change, it was possible to disable a control and then use focus traversal to reach it anyhow, and in the case of text fields, enter text into a disabled field.

Fixes #33985
