Incremental KAPT - track constants usage

This commit adds support for tracking of used constants in
source files. For every constant used in a source file, class
that defines the constant and the constant name are tracked.

Value of the constant can be obtained using
annotation processing APIs, so if the constant value changes, a source file
using it has to be reprocessed.
