The existing legacy performance.memory API accounts external string and array buffer backing store bytes. This CL adds per-context tracking of external bytes Bug: chromium:973627 Change-Id: I2b308dc540454e7b0b66406b83a18bf8f8d55d8e Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2025369Reviewed-by: Dominik Inführ <dinfuehr@chromium.org> Commit-Queue: Ulan Degenbaev <ulan@chromium.org> Cr-Commit-Position: refs/heads/master@{#66018}

This adds inference for general JSObjects to NativeContextInferrer in the case when the object is going to be attributed to the shard context.

This changes the marking worklist draining for the main thread marker and the concurrent marker to use the following algorithm in per-context mode: 1) Pop an object from the marking worklist. 2) Try to infer the native context that owns the objects. This is done using a new NativeContextInferrer class. 3) If the inference is successful, then change the active marking worklist to the worklist of the inferred native context. 4) Otherwise, keep the current active marking worklist. 5) Visit the object. Newly discovered objects will be pushed onto the active marking worklist. 6) Account the object size for the native context corresponding to the active marking worklist. This is done using a new NativeContextStats class. The main property of the algorithm is that each object for which we couldn't infer the native context is either attributed to the native context retaining it or is not attributed to any native context.
