Remove most content from Interpolation

The majority of the data and logic in the Interpolation base class is only
required for the LegacyStyleInterpolation subclass, and is ignored or
overwritten for InvalidatableInterpolation. This patch moves this data and logic
down the hierarchy into LegacyStyleInterpolation.

As additional consequences:
- SampleInterpolation classes defined in tests inherit from
  LegacyStyleInterpolation instead of the Interpolation base class
- getCachedValueForTesting is made pure virtual, requiring a placeholder
  implementation to be added to InvalidatableInterpolation, although this is not
  called anywhere

Remove unused code in InvalidatableInterpolation

This patch removes two functions in InvalidatableInterpolation that are
unreached: apply and getCachedValueForTesting.

Since InvalidatableInterpolation has cached values, I had originally intended to
supply a meaningful implementation for getCachedValueForTesting. However, after
further consultation, I'm instead removing the virtual function from the
Interpolation superclass and modifying the tests that use it to make it explicit
that they will be executing LegacyStyleInterpolation::getCachedValueForTesting.
