61a6fd84e1 [wasm] Rename "OnModuleCompiled" and related callbacks
Already after enabling Liftoff, the name did not match the semantics any
more. The callback was called after top-tier finished, not after initial
compilation of the module finished.
With dynamic tiering, the name is even less fitting.

This CL renames the "OnModuleCompiled" callback in the API to
"MoreFunctionsCanBeSerialized", which makes it more obvious what the
API should be used for. It also internally renames all related typedefs
and methods accordingly.

One call of the callback in the streaming decoder was already wrong
before this CL and is being removed.

b5e9eab6d0 [wasm] Fix module prefix hash for streaming decoder
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.

ae41f7dfd9 cppgc: Fix caged-heap reservation when pointer compression is enabled
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.

a537be463f [heap] Track unprotected chunks in LocalHeap
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.

31850be1c2 [inspector] Introduce status result for Debugger.setScriptSource
This CL introduces a new `status` enum returned by setScriptSource.
We'll use the information in the DevTools frontend to show more
meaningful error messages as well as disambiguate compilation errors
from failed live edits.

Drive-by: Deprecate the sync and async stack traces in the result.
Currently `setScriptSource` is guaranteed to stay paused so there
is no need to send along the same information from the
preceeding `Debugger.paused` event.
In the future we will restart the top-most frame once we allow
the top-most frame to be edited. In that case the inspector
fires Debugger.resumed + Debugger.paused events following the
live edit also making the info returned here superfluous.

75a4ddc953 Revert "Build cctest while building V8"
This reverts commit 7787ed2007.

Reason for revert: Seems to break the archive bot (https://ci.chromium.org/ui/p/chromium/builders/ci/linux-archive-dbg/b8811978830853167601/overview)

Original change's description:
> Build cctest while building V8
>
> I noticed in a recent build that C++ files from cctest didn't start
> compiling until after several slow non-parallel tasks such as running
> mksnapshot and linking v8_for_testing. I don't see any reason that
> cctest sources should wait for those tasks, so in this change I propose
> adjusting the build dependencies for more parallelism.

e831949f5e [test] Fix setting flags in SingleThreadedDefaultPlatformTest
We will not be able to modify flags after initializing V8 (soon).
The {SingleThreadedDefaultPlatformTest} was resetting flags during
teardown for no reason, as we do not support running multiple tests in a
row anyway. Thus remove that use of {SaveFlags} and just set the
--single-threaded flag before initializing V8.

8742d2a273 Reland "Allow lookup of matching scripts in Isolate compilation cache"
This is a reland of commit c443858fa9

The original version included an operation which could left-shift
signed values, which is undefined behavior; the updated version masks
the value first to avoid the problem.

Original change's description:
> Allow lookup of matching scripts in Isolate compilation cache
>
> Currently, if the same script text is compiled multiple times with
> differing details (such as name, line number, or host-defined options),
> then multiple copies of that script are added to the Isolate's
> compilation cache. However, any attempt to look up those scripts can
> find only the first instance. This change makes the script compilation
> cache behave more consistently by checking the details while searching
> the hash table for a match, rather than after a potential match has been
> found.
