Supports heap snapshots using the new @vscode/v8-heap-parser module. The parser runs in a Node.js worker_thread on the extension host, and is queried by postmessage RPC from connected webviews. This adds a table view and a cytoscape-powered graph view of retainers, in the 'flame' package, as seen in pacific standup yesterday. Most of the work in this PR is reworking the existing structures to support asynchronously loading data. Heap snapshots are _big_, far bigger than CPU profiles or heap profiles, so we don't want to load it into memory all at once.
