Bug 958714 part 1: Remove special case for flex & grid items' percent block-axis margin/padding resolution, to align with other browsers. r=mats a=IanN DONTBUILD CLOSED TREE SeaMonkey ESR52 release branch only. Now, flex and grid items will resolve percent margin and padding against their container's *inline-size*, even if the percent margin/padding is in the block axis. This matches the CSS2 behavior that's always existed in block containers. MozReview-Commit-ID: K3YXHpdqRHa

<!-- Testcase with percent-valued padding and/or margin on flex items.
     The spec allows these to be resolved against the flex container's
     inline size (regardless of which axis the percent padding/margin is in).
