Prior versions of GN had a bug (gn:22) where visibility rules
for configs weren't being enforced properly.
This CL tweaks the visibility settings of some configs to
conform to the latest version.

This patch replaces V8's tracing implementation (i.e., the TRACE_EVENT
macros) with the track event base implementation from Perfetto. The
advantages of doing this are:
1) This allows us to remove most tracing-related backend code from V8.
2) V8 can start writing strongly typed trace event arguments, which
are more compact, easier to process and more extensible than legacy
JSON-based trace arguments.
For the time being, we still support the old trace macros when V8 is
embedded into Chrome and other embedders.

In the process:
* Augment C++-generated Torque classes with SizeFor methods to
calculate size of instances.
* Add a new "@generateBodyDescriptor" annotation that causes Torque to
generate C++ BodyDescriptors code that can be used to visit objects
compatible with existing V8 mechanisms, e.g. GC
* Fully automate C++ macro machinery so that adding non-extern Torque
class doesn't require any C++ changes, including ensuring generation
of instance types and proper boilerplate for validators and
printers.
* Make handling of @export a true annotation, allowing the modifier to
be used on class declarations.
* Add functionality such that classes with the @export annotation are
available to be used from C++. Field accessors for exported classes
are public and factory methods are generated to create instances of
the objects from C++.
* Change the Torque compiler such that Non-exported classes implicitly
have the @generateBodyDescriptor annotation added and causes both
verifiers and printers to be generated.
* Switch non-extern Torque classes from using existing Struct-based
machinery to being first-class classes that support more existing
Torque class features.

This CL implements enums in Torque in three steps:
1.) It implements necessary changes to Torque's type system. In
particular, the constraints on constexpr types are relaxed such that
constexpr types can exist without a corresponding non-constexpr
version. Furthermore, constexpr and their non-constexpr counterpart
need not be of the same kind of type. This allows an AbstractType to
have a UnionType as its non-constexpr counterpart.
2.) The enum feature itself is realized as a pure desugaring in the
parser, where all required types, constants and macro specializations
(like FromConstexpr<>) are generated from a simple enum declaration,
such that enum entries are not just constants, but are namespace
scoped and have distinct types so that they can be used within
typeswitch constructs.
3.) Almost all of the existing constants defined in torque
(.tq files) are ported to new enum definitions.

The Torque formatter script did a hack to put spaces arount the | of
union types. This was broken when the inserted comment ended up on the
end of a line. For this reason, and since it doesn't make sense to
fight the Google-wide TypeScript style for union types, this CL reverts
to not putting spaces around union types.

Host info used to be stored on the global reference underlying a Ref;
now it is stored in a JSWeakMap and hence tied to the lifetime of the
actual object on V8's heap.
Additionally, the internal metadata needed for C-API functions is now
stored on the SharedFunctionInfo and no longer overlaps with the host
info mechanism.
