Question mark icon RTL

[driskull]

Use case: User is asking for the question-mark icon but reversed to be used in RTL languages.

In calcite-ui-icons there are some RTL icons provided already such as list-number-rtl. Is it the plan to provide RTL icons for every scenario necessary? If so, can the reversed question mark icon be added?

If not, would it be possible to document which icons are able to be mirrored for RTL viewing? For example, checkbox icons shouldn't be flipped but a question-mark is ok to flip. It would be helpful to know this information so icon usage is consistent and we aren't flipping icons we aren't supposed to.

It would also be nice to have this information stored in a JSON file so we could know which are allowed to be flipped/mirrored. It might be useful to have metadata like this for each icon because you could show relationship data like name the flipped version or the left/right equivalent.
