[kernel, vm] Revise how metadata is written in kernel binaries Metadata is no longer written ahead of all nodes. Instead, metadata for each node is written in the same context as the node itself (into a separate buffer). This allows metadata to contain (serialize) arbitrary nodes (for example, arbitrary DartTypes) and use serialization context of parent nodes (such as declared type parameters). However, with this change metadata looses the ability to reference arbitrary AST nodes. This ability was overly restricted and had no practical uses. (It was not possible to reference nodes which are not reachable from root Component. As a consequence, it was not possible to write references to arbitrary DartTypes.) This change aligns the serialization capabilities of metadata with how kernel AST nodes are serialized.
