[css-break] 'orphans' and 'widows' property should have '2' as initial value

[Ahmad Saleem]

Hi Team,

While going through failing WPT test, came across following two failing where we don't have initial value for 'orphans' and 'windows' and return 'auto' instead of '2' as per spec.

Failing WPT Test: https://wpt.fyi/results/css/css-break/inheritance.html?label=master&label=experimental&aligned=&q=inheritance

sub-test names: Property orphans has initial value 2 & Property widows has initial value 2

Web-Spec: https://drafts.csswg.org/css-break/#property-index

I tried to look into CSSProperties.json whether we have way to do 'initial value' similar to Chromium bug couldn't figure out.

Just wanted to raise so we can fix it.

Thanks!

removing all code related to `hasAutoOrphans` and `hasAutoWidows` should just work:
https://searchfox.org/wubkat/search?q=hasAutoOrphans&path=&case=false&regexp=false
https://searchfox.org/wubkat/search?q=hasAutoWidows&path=&case=false&regexp=false

(although some of these checks will need to be replaced with `style().orphans() == RenderStyle::initialOrphans()` or something similar)
