Added font-icons-mdl2 package to 7.0

[GeoffCoxMSFT]

This allows callers migrating from v7 to v8 to to using the @fluentui/ namespace and the same package name as v8 while remaining on v7. This provides a path for incremental upgrade.

Issues

Updates #24393

[msft-fluent-ui-bot]

It looks like this change to the 7.0 branch may not have been submitted to master yet. Now that version 8 has released, all changes must be submitted to the master branch first (except in emergencies or if the change is irrelevant to version 8).

Please do one of the following:

• If you've already created a PR to master, add a link to it
• If the change is irrelevant to version 8, add a comment explaining why
• Otherwise, create a PR to master with this same change, and add a link to it

After that, you can dismiss this review and remove the "needs cherry-pick" label (or ask a team member to help do so).

Want to avoid this in the future? Include text like "Cherry-pick of ####" in the PR description (where #### is the real master PR number).
