bindings: Add dependencies on generated files

Code in Blink depends on some generated code in general.
And its dependencies can be indirect.  For example,
  t/b/r/bindings/modules/v8/properties_per_feature_installer_for_testing.cc
includes
  t/b/r/bindings/core/v8/v8_origin_trials_test_dictionary.h
through some other header files.  But they have no dependency chain
in GN file, and thus flaky compile errors can happen.

This CL adds dependencies to connect a target to compile the .cc file
and a target to generate the .h file.
