avoid building static libs on windows when BUILD_SHARED_LIBS=ON

except all flags_* libraries, for which DLL builds on windows
are not supported

To do this, expand list of ABSL_INTERNAL_DLL_TARGETS; this
is due to how the logic of absl_internal_dll_contains checks
whether additional static libraries should be built, compare
