[vm] Encapsulate lookup of Symbol members in ObjectStore

For members of program structure that we cache in the ObjectStore we try
to provide only read-only access in the public API. The lazy population
is encapculated in the ObjectStore class.

Use the same mechanism we use for core/isolate/... library members also
for the `dart:_internal` members.

Furthermore cache the Symbol._name field in the ObjectStore to avoid
expensive lookup as well as avoid an extra TLS lookup.

TEST=Existing test suite.
