deps: cherry-pick dbfe4a49d8 from upstream V8
Original commit message: Introduce ScriptOrModule and HostDefinedOptions This patch introduces a new container type ScriptOrModule which provides the name and the host defined options of the script/module. This patch also introduces a new PrimitivesArray that can hold Primitive values, which the embedder can use to store metadata. The HostDefinedOptions is passed to V8 through the ScriptOrigin, and passed back to the embedder through HostImportModuleDynamically for module loading. Bug: v8:5785, v8:6658, v8:6683 Cq-Include-Trybots: master.tryserver.chromium.linux:linux_chromium_rel_ng Change-Id: I56c26fc9a680b273ac0a6691e5ad75f15b8dc80a Reviewed-on: https://chromium-review.googlesource.com/622158 Reviewed-by: Adam Klein <adamk@chromium.org> Reviewed-by: Georg Neis <neis@chromium.org> Commit-Queue: Sathya Gunasekaran <gsathya@chromium.org> Cr-Commit-Position: refs/heads/master@{#47724} Backport-PR-URL: #17823 PR-URL: #16889 Refs: v8/v8@dbfe4a4 Refs: #15713 Reviewed-By: Ben Noordhuis <info@bnoordhuis.nl> Reviewed-By: Michaël Zasso <targos@protonmail.com>
