Backports PR #9014 **Commit 1:** Speed up rendering of large docs in doc table Back in 2014 a utility was added to insert <wbr> (word break opportunity) tags into doc table fields to improve their display in the browser. This utility looped over every character in _source when it was selected as a column in the doc table, which it was be default. That really started to slow things down when displaying large docs. I compared how the browser renders things with and without the <wbr>'s and there's almost no difference, certainly nothing as dramatic as shown in the linked PR which added this word breaking functionality. Perhaps browsers have improved in the last two years, or perhaps something changed in our CSS. Since we're getting no or negligible value from this utility and it makes Discover impossible to use with large docs, I simply removed it.

Speed up rendering of large docs in doc table
Back in 2014 a utility was added to insert (word break opportunity)
tags into doc table fields to improve their display in the browser. This
utility looped over every character in _source when it was selected as a
column in the doc table, which it was be default. That really started to
slow things down when displaying large docs. I compared how the browser
renders things with and without the 's and there's almost no
difference, certainly nothing as dramatic as shown in the linked PR
which added this word breaking functionality. Perhaps browsers have
improved in the last two years, or perhaps something changed in our CSS.
Since we're getting no or negligible value from this utility and it
makes Discover impossible to use with large docs, I simply removed it.

Commit 2:
Improve word breaking in doc table
To maintain similar word breaking without adding tags I've added
some css styles that do essentially the same job. word-break: break-word
gives us the best formatting but it's not a part of the standard yet
(see link below) so I provided an almost-as-good fallback with
break-all.
