[3.9.3] Core compilation breaks in Typescript 3.7.2

[bentona]

node_modules/@material-ui/core/Portal/Portal.d.ts:2:10 - error TS2440: Import declaration conflicts with local declaration of 'PortalProps'.

2 import { PortalProps } from '../Portal';
           ~~~~~~~~~~~

Found 1 error.

There was a fixed pushed for 4.x here:
#18213
#17676 (comment)

Can we backport this to 3.9?
