Bug 1933408 part 1: Implement layout support for 'stretch' as a block-axis size (with '-webkit-fill-available' as an alias). r=TYLin

Browse Source 
Note that both keywords are disabled in the CSS parser for now, behind
these about:config prefs:
layout.css.stretch-size-keyword.enabled
layout.css.webkit-fill-available.enabled

Prior to this patch, we handled both keywords as pure aliases for
'-moz-available' (which has the correct 'stretch' behavior in the inline axis
but which just behaves like the initial value in the block axis).

This patch changes that so that 'stretch' and '-webkit-fill-available' will now
actually do the right thing in the block axis (if they're enabled at all, via
their aforementioned about:config prefs).

The relevant spec text here is:
https://drafts.csswg.org/css-sizing-4/#valdef-width-stretch
https://drafts.csswg.org/css-sizing-4/#stretch-fit-sizing
