This API allows the embedder to provide a stack and PC, FP and
SP registers. V8 will then attempt to unwind the stack to the C++ frame
that called into JS. This API is signal-safe, meaning it does not call
any signal-unsafe OS functions or read/write any V8 state.

This is to ensure the snapshot is deterministic.
Internal fields can contain:
- reference to heap object
- embedder-defined aligned pointer
- a smi
The latter two are not distinguishable by V8, so if the serializer
callback returns non-zero value, we consider it to be an aligned pointer
and clear it to ensure that the snapshot does not contain memory
addresses that may not be deterministic. If the callback returns
{ nullptr, 0 } as result, we consider it to be a smi or some in-place
data that we then serialize verbatim.

1) The CL extracts platform-specific code into separate files, see
https://docs.google.com/document/d/1HCgKIpdjy_CEodTLvZ5VuykDI6gGTHrTtau2j0zwm28.
Specifically this means:
* Move posix-specific API functions from v8.h to v8-wasm-trap-handler-posix.h.
Deprecate the existing TryHandleSignal API function.
* Move posix-specific function declarations from trap-handler-internal.h to
handler-inside-posix.h
* Move posix-specific function definitions from handler-shared.cc to
handler-outside-posix.cc
2) The CL changes filenames from *-linux.* to *-posix.*. I expect that
most of the implementation for MacOS will be the same as for Linux.

with a usable structure. If, as is sometimes the case, a v8::StackTrace

Splits background compilation data out of ScriptStreamingData and into
BackgroundCompileTask. Also makes BackgroundCompileTask no longer a sub-class
of ScriptStreamingTask, and instead have ScriptStreamingTask delegate to a
BackgroundCompileTask.
As part of this change, we now create the CharacterStream on the main thread,
and therefore have to set the (thread-local) runtime_call_stats on the already
created CharacterStream when the BackgroundCompileTask is run on the background
thread. As such, changes to CharacterStream were needed to feed the
runtime_call_stats through appropriately.
Deprecates Source::GetCachedData and StreamedSource::GetCachedData since they are
no longer used, and the streamed source never has cached data (streaming is
suppressed if cached data is available). Also removes Utf8ChunkedStream which
is dead code.

This is more generic as it doesn't restrict embedded code to just
builtins. Also, some builtins are still on-heap so the name was not
totally accurate.
