deps: make V8 9.2 abi-compatible with 9.0

Revert "[api] Avoid handles for const API functions"
This reverts commit aee471b2ff5b1a9e622426454885b748d226535b.

Revert "[api] Remove deprecated [Shared]ArrayBuffer API"
This reverts commit 578f6be77fc5d8af975005c2baf918e7225abb62.

Revert "[Jobs]: Cleanup in v8 platform."
This reverts commit baf2b088dd9f585aa597459f30d71431171666e2.

Revert "Skip global registration of [Shared]ArrayBuffer backing stores"
This reverts commit fcdf35e6d70d51699ece063e25dc705e80673308.

Revert "[api] Remove previously deprecated Function::GetDisplayName()."
This reverts commit 6165fef8cc9dde52973e54c915e6905221b3f8fb.

Revert "[api] Remove deprecated Symbol::Name()"
This reverts commit bbc72ef6c7d6d8e2c4dd074d7713e5c841003163.

Revert API change for HeapProfiler::TakeHeapSnapshot
This reverts a small part of 7f52e4f92d3d3ded9a1701ee2f93966075ae5004.

Revert "[cpu-profiler] Reintroduce support for context filtering"
This reverts commit 0aacfb2a6ecbeda1d1d97ca113afd8253a1b9670.

Restore new argument for TakeHeapSnapshot method
This creates a new TakeHeapSnapshotV8_92 method with the signature from
7f52e4f92d3d3ded9a1701ee2f93966075ae5004.
It is necessary because the API is used internall by V8.

Silence irrelevant warning
V8 triggers it in the Name method.

Revert "[api] Add v8::metrics::LongTaskStats for the LongTasks UKM"
This reverts commit 521ae93bf652b0cc1fec1fdd788e3b80fb72a349.

Move cage_base isolate data field
Makes 3ada6f27404b4ffd6d3e97cf15be76672f60c10d ABI-compatible.
