fix(component-sidenav,component-viewer): fix sticky TOC (angular#917)

- remove `overflow: hidden` that breaks TOC stickiness
  - made sure to keep the Material Table examples from overflowing afterwards
    via changes to `component-viewer.scss`
- revert change from angular#784 to make small breakpoint 939 instead of 959 as it
  isn't consistent with our Sass breakpoints or the Material layout spec
- use alternative to `router-outlet + *` styling
- use constants for more media query breakpoints
- add some missing Sass imports
- move $sidenav-width to constants
- update constants to include different horizontal padding for
  guides and sidenav content
- update copyright year
- add stylePreprocessorOptions for shorter Sass imports
- add .nvmrc since Angular projects only support NodeJS 12 atm

Fixes angular#257
