This PR adds support to dynamically update the direction (rtl|ltr) of the Grid component. The implementation is partially based on the equivalent of https://github.com/bvaughn/react-window/blob/master/src/createGridComponent.js

Direction of ltr has no effect on the actual implementation and should produce no changes. Setting rtl however will make the Grid be scrollable from the right, and column 0 will be the first starting from the right.

Running example at https://albertfdp.github.io/react-virtualized/#/components/Grid

• The existing test suites (npm test) all pass
• For any new features or bug fixes, both positive and negative test cases have been added
• For any new features, documentation has been added
• For any documentation changes, the text has been proofread and is clear to both experienced users and beginners.
• Format your code with prettier (yarn run prettier).
• Run the Flow typechecks (yarn run typecheck).

Thanks @albertfdp !
We forked your repo, merged the grid-rtl branch to master and published it to npm in order to support rtl in our website.
Your rtl support is on our production code and works good :)
Until this pull request will be merged, you can use the package that we published to npm:
https://www.npmjs.com/package/react-virtualized-carwiz

Sorry for the very long delay in getting back to you about this!

I've just finished a large update for version 10 of react-virtualized (#1900): the library has been rewritten in TypeScript, every component is now a function component (React 18+ is required), and the source moved from source/ to lib/. Because of that, this PR can't be merged as-is. Version 10 still doesn't support RTL layouts.

If you're still interested in this change, I'd welcome a new PR with it rebased onto the version-10 branch (or onto master once version 10 has been merged).
