This patch fixed the following:
1. Make the helper support the vertical writing modes since its callers
GetMinISize() and GetPrefISize() are fully aware of the vertical writing modes.
`overflow-scroll-intrinsic-001.html` verifies this scenario. This also fixed a
testcase with "writing-mode: vertical-lr" in flexbox's
cross-axis-scrollbar.html.
2. Treat scrollbar's intrinsic size "zero" if we have "scrollbar-width: none"
since no scrollbar is showing at all.
`overflow-auto-scrollbar-gutter-intrinsic-003.html` verifies this scenario.
3. Return the scrollbar size if we have "scrollbar-gutter: stable", or twice the
size if we have "scrollbar-gutter: stable both-edges".
`overflow-auto-scrollbar-gutter-intrinsic-{001,002}.html` verifies this
scenario.
