fix(material-experimental/mdc-tabs): support backgroundColor on nav bar (#21746)

crisbeto · annieyw · commit 9f3e3e4d53cb · 2021-02-05T17:59:38.000+08:00
Fixes that the MDC-based `mat-tab-nav-bar` doesn't support a `backgroundColor`. This is something we support on the non-MDC version, but it didn't make it into the MDC one for some reason. (cherry picked from commit da5e2eb)
