[LayoutNG] Disable line-break collapsing rule for East Asian Width

CSS Text Level 3 has a rule for collapsing line break for
East Asian writing systems that do not use spaces to delimit
words. The rule is based on Unicode East Asian Width
property, but recently it was brought to the attention that
the rules may need more logic at:
https://github.com/w3c/csswg-drafts/issues/337

As the discussion seems to take longer to resolve, and there
is a possibility to change the rules in the current spec,
this patch disables the rule until WG reaches to a consensus.

LongFind.txt was changed in r616898 (CL:1379086) when find-
in-page switched to NGOffsetMapping. Since this CL changes
whitespace collapsing rules for East Asian text back to
the same as legacy, the test data change is reverted.
