Reland "Add cr.exportPath() to ESLint banned properties"

This reverts commit 87042ab605.

Reason for revert:

Clean up CLs have now landed and support for cr.exportPath() is
being removed from Closure Compiler's --chrome_pass.

It'll still have runtime effects, but the compiler wont understand
that cr.exportPath('a.b.c') translates to window.a.b.c.
