This is a performance fix. It avoids the cost of XML/HTML translations
for fields that may not be necessary when prefetching fields on records.
This patch marks such fields as non-prefetchable by default.
The code that changes the attribute `translate` on HTML fields (from
`translate=True` to `translate=html_translate`) has been adapted to
allow the setup of textual fields to mark the field as non-prefetchable.
Jairo Llopis made a comparative benchmark: evaluating `name_get` on
`event.event` records. The method needs the field `name` and without
the patch, the prefetching mechanism reads the translated HTML field
`description` as well. This patch speeds up the benchmark from 5800ms
to 800ms (see https://github.com/odoo/odoo/pull/37967#issuecomment-538364011).
