Stack.Layout and Flex.Layout caused a lot of heap allocations / escapes. The
reason was that scratch space for dims and call and was inside Stack/FlexChild.
child.call.Add(gtx.Ops) confused the go escape analysis and caused the entired
children slice to escape to the heap, including all widgets in it. This caused a
lot of heap allocations. Now the scratch space is separate from children, and
for cases len(children) <= 32, we will allocate the scratch space on the stack.
For cases len(children) > 32, only the scratch space gets allocated from the
heap, during append.
