commit 772fbff236bdf680788846586a34e9f4d074b2c5

DOM: NodeIterator.filter and TreeWalker.filter should return values which were specified to createNodeIterator/createTreeWalker.

We used to return values wrapped by NodeIterator interface. The DOM specification
doesn't define such behavior, and Edge, Firefox, and Safari do not.

The core part of this CL is CPP_VALUE_TO_V8_VALUE in v8_types.py. We return a v8
value stored in V8NodeFilterCondition.

Because we don't need to wrap values by NodeFilter, this CL has simplification like:

- Cleanup of indirection ownership;
 Old: NodeIteratorBase -> NodeFilter -> V8NodeFilterCondition as NodeFilterCondition
 New: NodeIteratorBase -> V8NodeFilterCondition

- Removal of a V8PrivateProperty
 It can be replaced with TraceWrapper.

This CL fixes 1,106 failures in external/wpt/dom/.
