feat(mat-icon): Create an injection token for setting icon-defaults

[yusijs]

Feature Description

I would like to have an injection token, allowing me to easily override the default fontSet without using the MatIconRegistry service.

Use Case

My particular use case right now is for storybook, where I would now need to create a wrapper around all components and call the registry-service. Being able to just { provide: MAT_ICON_OPTIONS, useValue: { color: 'primary', fontSet: 'material-icons-outlined' } would be timesaving.
