[LayoutNG] Estimate the capacity of NGInlineItemsBuilder

Currently, 50 to 60% of CollectInlines are spent in
ExpandCapacity to reallocate the vector buffer. This patch
makes rough estimation from the number of direct children
to reduce the number of reallocations.

Currently, slow tests such as storage/indexdb/* creates
more than 1,000 items by appending the test results in
<span></span><br> structure. This patch reduces vector
allocation in such cases to once or twice.
