tests.
Report an error if the native segment for an TRTEngineOp is executed. This
ensures that the TRTEngineOp constructed by the bridge is acceptable to
TensorRT to catch bugs.
Modify TrtModeTestBase to not build static engines for a graph that generates
dynamic shaped values. This avoids native segment execution that is not caused
by the inconsistency between the bridge and TensorRT.
Temporarily allow native segment execution for VGGBlockTest and
VGGBlockNCHWTest to workaround b/159459919.
