deps: V8: cherry-pick semver-major commits from 10.2
Includes the following commits: commit b2978927d8a96ebc814cccbc5a9f1c35910ee621 Remove dynamic map checks and custom deoptimization kinds This CL removes: - Dynamic map checks aka minimorphic property loads (TF support, builtins). - "Bailout" deopts (= drop to the interpreter once, but don't throw out optimized code). - "EagerWithResume" deopts (= part of dynamic map check functionality, we call a builtin for the deopt check and deopt or resume based on the result). Fixed: v8:12552 Change-Id: I492cf1667e0f54586690b2f72a65ea804224b840 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3401585 commit f52f934119635058b179c2359fe070b8ee0f9233 PPC/s390: Remove dynamic map checks and custom deoptimization kinds Port b2978927d8a96ebc814cccbc5a9f1c35910ee621 Original Commit Message: This CL removes: - Dynamic map checks aka minimorphic property loads (TF support, builtins). - "Bailout" deopts (= drop to the interpreter once, but don't throw out optimized code). - "EagerWithResume" deopts (= part of dynamic map check functionality, we call a builtin for the deopt check and deopt or resume based on the result).

Also saves a word per v8::TracedReference as there's no need to keep a possible callback around.

Change-Id: I413fafc8658e922fd590e7fe200600a624f019a6 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3557253 commit cff2b5000a1aa417a9c4499bcfa3ffda4542f4f1 Deprecate signature checks in Set{Accessor,NativeDataProperty} Change from V8_DEPRECATE_SOON to V8_DEPRECATED. It turned out that we don't have to make changes in chrome code, so we can go to deprecated right away. Bug: chromium:1310790 Change-Id: I1bd529536d3a0098f11f13b3e44fe3dbc80eed04 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3571897 commit 9238afb0c0ee52c9111a7e9f2f055137628771ad Allow embedder to set global OOM handler Embedders can currently specify a callback for OOM errors during Isolate initialization. However, there are cases where an OOM error can be thrown in a context where we don't have access to an Isolate, for example on a task posted to a worker thread. This CL introduces an initialization API to allow the embedder to specify a process-wide OOM callback. Bug: chromium:614440 Change-Id: I326753d80767679f677e85104d9edeef92e19086 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3561916 commit ca51ae3ac8b468509603633adb6ee3b3be9306ec [api][profiler] Get StartProfiling, StopProfiling to accept integer ID rather than string This CL adds support for interacting with CpuProfile with their integer id. A String ID is problematic because it forces an allocation when stopping or cancelling a Profiler which can happen during a GC when this is not allowed.
