update_engine: Split Extent utils from graph_utils.

"Graph" related utils should only concern parts of the code using the
inplace generator, since other generators don't use a dependency graph.

This patch splits the Extent related utils from the graph related ones
creating a new extent_utils.h file.

BUG=None
TEST=unittest still pass.
