Introduce LocalAndroidColorScheme to expose Android colors

This CL introduces the AndroidColorScheme and its CompositionLocal to
access any Android color from a Composable. The list of colors was taken
from [1].

Ideally we would only use M3 colors but given that M3 and Android
colors have not been aligned yet, our current UI specs are still using
the Android colors.

In the long term, this class will be deleted or slimmed down to contain
only the few colors missing from M3.
