The change https://chromium-review.googlesource.com/c/v8/v8/+/2572173
implemented HostGetSupportedImportAssertions [1] in a fairly literal
sense, where the host supplies a list of supported import assertions
and V8 filters the import assertions in a ModuleRequest and exposes
only supported assertions via its API surface.
However, we've decided that the interop guarantees provided
by doing the filtering in V8 are probably not worth the added
complexity. Thus, this change removes the filtering. Going forward,
hosts will be expected to ignore unknown asserions received from V8.
This is mostly a revert of
https://chromium-review.googlesource.com/c/v8/v8/+/2572173, with
v8::Isolate::CreateParams::supported_import_assertions being kept
for now (since we first have to delete the Blink code that sets it),
and a new comment in v8.h instructing hosts to ignore unknown
assertions.

Implement the HostGetSupportedImportAssertions, whose purpose
is to filter the list of import assertions exposed to the embedder to
only those assertion with keys that the embedder recognizes. See
https://tc39.es/proposal-import-assertions/#sec-hostgetsupportedimportassertions.
This change doesn't actually implement it as a callback, but instead
passes the supported assertions during creation of the Isolate via
CreateParams. This expresses clearly the requirement that the supported
assertions must never change for the lifetime of the Isolate.
Note that we still need to maintain all assertions in a map
while parsing the import assertions clause, because duplicate keys for
an unsupported assertion still needs to be detected as a parse error. So,
the filtering is done later during
SourceTextModuleDescriptor::AstModuleRequest::Serialize.
The actual filtering algorithm simply iterates the assertions and the
supported assertion keys in a nested loop. There's currently only one
assertion in use ("type"), so there should be no reason to get too
clever here unless at least several more assertions are generally
supported.

The rest of the code base was already migrated last year in
https://crrev.com/c/1631409. In the API we have to be more careful to
not break embedders. According to the standard there is no semantic
difference between typedef and using ([decl.typedef#2]):
A typedef-name can also be introduced by an alias-declaration. The
identifier following the using keyword becomes a typedef-name and the
optional attribute-specifier-seq following the identifier appertains
to that typedef-name. Such a typedef-name has the same semantics as if
it were introduced by the typedef specifier.
Thus this CL replaces all typedefs in include/v8.h by the equivalent
using declaration. This improves readability, especially for function
pointer types.

Add a method that returns the microtask queue that is being used
by the `v8::Context`.
This is helpful in non-monolithic embedders like Node.js, which
accept Contexts created by its own embedders like Electron, or
for native Node.js addons. In particular, it enables:
1. Making sure that “nested” `Context`s use the correct microtask
queue, i.e. the one from the outer Context.
2. Enqueueing microtasks into the correct microtask queue.
Previously, these things only worked when the microtask queue for
a given Context was the Isolate’s default queue.
As an alternative, I considered adding a way to make new `Context`s
inherit the queue from the `Context` that was entered at the time
of their creation, but that seemed a bit more “magic”, less flexible,
and didn’t take care of concern 2 listed above.

Although every Primitive is a Data, the Cast operations for the
subclasses of Primitive do not allow casting directly from Data to the
subclasses without first going through Value. Because of this,
Primitives extracted from a V8::FixedArray require two casts to get to
the "real" type.
Thus, as a convenience to embedders, this change makes it possible to
cast directly from Data to all the subtypes of Primitive.
Also, this change makes the parameter names in the declarations match
those in the definitions, though there does not seem to be a universally
followed convention regarding these.

Previously V8 would wrap the WebAssembly.Memory backing stores into
Uint8Arrays and report that as memories, but that's confusing to the
developer, since that's not what's really being used. The way that
DevTools presents the backing stores of memories, it's still perfectly
possible to get hold of an Uint8Array if that's what the developer is
looking for.
To make it possible to easily identify the WebAssembly.Memory objects
in the DevTools front-end (in particular for the memory inspector) we
add a 'webassemblymemory' subtype to the Chrome DevTools Protocol. We
also improve the description for the memories to include the number
of active pages.

https://docs.google.com/document/d/1yuXgNHSbTAPubT1Mg0JXp5uTrfirkvO1g5cHHCe-LmY/edit#heading=h.q0c9h4p928mn
such that a v8::Module exposes module requests as a FixedArray of
ModuleRequest objects, which can then be used to obtain their module
specifier and source code offset. This replaces the old functions that
passed back individual specifier Strings and Locations via repeated
calls to getters that take an index. These are marked as deprecated.
The new ModuleRequest interface includes a getter for an
ImportAssertions FixedArray, which will contain the import assertions
for the request if --harmony-import-assertions is set, and will be
empty otherwise.
One notable change here is that the APIs now return source code offsets
rather than v8::Locations. The host must then call the new
Module::SourceOffsetToLocation to convert these offsets into line/column
numbers. This requires a bit more back-and-forth, but allows the host to
defer the cost of converting from source offset to line/column numbers
until an error needs to be reported, potentially skipping the work
altogether.

pattern, an exception is thrown on creation of the regexp.
The commit also adds a new global V8 flag and changes an existing one:
* --enable-experimental-engine, which turns on recognition of the RegExp
'l' flag. Previously this flag also caused all supported regexps to
be executed by the experimental engine; this is not the case anymore.
* --default-to-experimental-regexp-engine takes over the previous
semantics of --enable-experimental-regexp-engine: We execute all
supported regexps with the experimental engine.

Chrome is currently adding a 128-bit V8ContextToken to keep track of
V8 contexts across multiple isolates and processes. Having per-isolate
token exposed by V8 leads to confusion of these two tokens.
This moves v8::Context::Token to v8::metrics::Recorder and changes
the corresponding functions:
- v8::Context::GetToken => v8::metrics::Recorder::GetContextId
- v8::Context::GetByToken => v8::metrics::Recorder::GetContext
This CL is purely mechanical and does not change the behaviour.

explicit names. The old values are updated as aliases to the new

enum to v8-platform.h so that it can be reused by cppgc.
Depracating individual values in an enum is supported by GCC only
since version 6. Thus new macros were needed for the deprecation
(which delegate to the existing macros when supported). GCC versions
older than 6 are still used by the CQ bots.

respective types.
C++11 introduced standard library helpers to express this more
naturally. The most direct translation would have been to use
{std::is_assignable} or {std::is_convertible} on the pointer types, but
in most cases we can be even more strict and force one type to be a
proper subtype of the other.
The only exception is {ReturnValue}, which allows to assign anything if
it's void.
