Introduce tone-based surfaces and accent color add-ons - Part 2 (#138521)
This PR is to introduce 19 new color roles and deprecate 3 color roles in `ColorScheme`.
**Tone-based surface colors** (7 colors): 
* surfaceBright
* surfaceDim
* surfaceContainer
* surfaceContainerLowest
* surfaceContainerLow
* surfaceContainerHigh
* surfaceContainerHighest

**Accent color add-ons** (12 colors):
* primary/secondary/tertiary-Fixed
* primary/secondary/tertiary-FixedDim
* onPrimary/onSecondary/onTertiary-Fixed
* onPrimary/onSecondary/onTertiary-FixedVariant

**Deprecated colors**:
* background -> replaced with surface
* onBackground -> replaced with onSurface
* surfaceVariant -> replaced with surfaceContainerHighest
