Make pnpm process-icons remove icons no longer in assets

[ravicious]

I noticed that after running pnpm process-icons, not all files in web/packages/design/src/Icon/Icons/ get updated. We should do rm web/packages/design/src/Icon/Icons/* before generating icon files.

Some icons are still used in the project:

$ rm -rf web/packages/design/src/Icon/Icons/*
zsh: sure you want to delete more than 100 files in /Users/rav/src/teleport/web/packages/design/src/Icon/Icons [yn]? y

$ pnpm process-icons

> [email protected] process-icons /Users/rav/src/teleport
> node web/packages/design/src/Icon/script/script.js & pnpm prettier --log-level silent --write 'web/packages/design/src/Icon/**/*.tsx'

Generated Icons.
Generated index.ts file.
Generated stories.

Found 2 errors.

From what Bartosz has found, MobileCamera got renamed to DeviceMobileCamera. InfoFilled is basically Info, but using fill instead of color for the icon color, so we need to replace it and just make sure it doesn’t appear odd.
