Before this CL, the heap object name of unnamed objects(those not
inheriting from NameProvider) would be solely determined by whether the
build-time configuration cppgc_enable_object_names is enabled.
This patch adds a way to override that value at runtime. This is
useful for preserving default behavior with custom builds but at the
same time allow them to still enable the feature.

Adds NameProvider to allow specifying names of objects. The
corresponding internal NameTrait is registered with the GCInfo object.
Use name infrastructure to provide a hint on encountering an unmarked
object in the marking verifier.
