Adds Module::GetStalledTopLevelAwaitMessage() API which searches for modules that have no pending async dependencies but have not yet resolved. An embedder may call this API when they are about to exit to check if TLA evaluation has stalled and provide a better error message.

Use the field index to look up the descriptor for double fields, and add a dependency on them. Drive-by, fix store field optimisation to only emit the optimised direct store for tagged fields, so that we don't accidentally insert HeapNumbers into double fields (making them mutable).

roll_merge.py manually checks out V8 into a temporary directory, locally builds a cherrypick, and uploads this to Gerrit. However, Gerrit has its own REST API which allows cherrypicking. Using this API directly has two advantages: 1) We don't need to perform any local checkouts, so it's much faster, and 2) The cherry-picked commit is marked as a cherry-pick by Gerrit, which means Rubber-Stamper-Bot will treat it as a cherry-pick. The implementation for now is very simple, and doesn't support things like cherry-picking multiple revisions or applying an additional local patch. It does, however, increment the patch value in v8-version.h, and tries to set Owners-Override +1.

The module's "prefix hash" is based on a prefix of the module bytes that starts at the beginning of the module and stops at the code section. In the case of the streaming decoder, if the code section is empty, `AsyncStreamingProcessor::ProcessCodeSectionHeader()` is never called, and we keep accumulating bytes in the hash after the code section. Fix this by always calling into the streaming processor even if the code section is empty.

Currently, PageAllocator assumes that FreePages(start, size) will always be called on the same region that was passed to AllocatePages(start, size). This assumption is made in: 1) leak-sanitizer (LsanPageAllocator) that checks it explicitly, 2) on Windows, FreePages() calls VirtualFree() with zero-size and MEM_RELEASE, which causes the entire reservation to be freed. The CL temporarily fixes the bot failures just by holding the unneeded half and adds a TODO to return the unneded part back to the OS.

The allowlist used for `Deoptimizer::IsValidReturnAddress` depends on fixed embedded builtin addresses. Pass a pointer to the isolate to this method, so that it can discover the actual builtin code start (which may have been remapped) and calculate the offset from the start of the builtins' code in order to check if the return address is allowed. After this change, do not disable short builtin calls when CFI is enabled. There's an important TODO for this change: Since the builtin code pointer that's used to check whether a return address is allowed is now writable, we should use pointer authentication to protect it.

CodePageCollectionMemoryModificationScope now increases a per-thread counter and inserts unprotected code chunks into a thread-local set of chunks. This information is moved from Heap into LocalHeap. We can't use kMaxWriteUnprotectCounter on the unprotect counter on the MemoryChunk anymore, since e.g. for concurrent Sparkplug N threads might now allocate a code object on the same page and since CodePageCollectionMemoryModificationScope doesn't know about the other threads anymore, each thread has to increase that counter by 1. We DCHECK that nesting depth now in the scope's constructor instead. We still need to remove chunks from `unprotected_memory_chunks_` when freeing an executable MemoryChunk during GC. Fortunately we can still do this, since all threads are in a safepoint during GC and we can remove the chunk from each thread-local set without any synchronization.
