Use checkdeps to ensure API headers don't include internal headers.

This CL updates the checkdeps configuration for the api/ folder in
order to explicitly avoid to #include non API headers from API headers.

In order to force a careful review of potential exceptions to this
rule, the CL also adds mbonadei@ and kwiberg@ as OWNERS of api/DEPS.
