Fix T66373: Strange translation text behaviour.

i18n code does not work from threads on some plaforms, so it is disabled
in Blender when called from non-main thread.

Means that we have to go to a slightly different approach, with dirty
tag and generating string on request for UI.

Note: Also had to update the `info` string size, to fit with expensive
asiatic scripts in utf-8... Using mem for that kind of runtime data is
not really nice, but for now it will have to do.
