This CL adds 2 new values to the EmbedderStackState enum with more
explicit names. The old values are updated as aliases to the new
values and marked as soon to be deprecated. This CL also moves the
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.

Summary of changes:
- GC visitors no longer rely on superclass visitors, but instead visit
everything themselves. This enables generating better code.
- Try to match simple body descriptors to reduce the amount of generated
code.
- Turn SizeFor(instance) into an AllocatedSize() method.
- Remove the special handling of resizable object sizes from Torque
and instead overwrite AllocatedSize in classes that need special
handling in C++.
- Split the visitor id lists depending on whether the class has pointer
fields.
- Turn Torque-generated body descriptors into an .inc file to
simplify includes.
- Fix generated size functions to properly align the size.
- Generate GC visitors (and C++ class definitions) for all string
classes and FixedArray, WeakFixedArray, and WeakArrayList.
- Store generated instance types in Torque class types. This is only
used to determine if a type has a single instance type in this CL.

We originally moved this protector to the native context to avoid
cross-native-context pollution of protector state. Ideally,
invalidating a protector in one NC should not affect any other NC.
But as it turns out, having the protector on the NC causes more
problems than it solves since all affected callers now need to find
the correct native context to check. Sometimes (e.g. in CSA regexp
builtins) it is possible to blindly check the current NC, but the
reasoning behind this optimization is tricky to understand.
Sometimes, fetching the correct NC is not possible due to access
restrictions. These implementation complexities outweigh the (unknown)
potential performance benefits.
In the future we should attempt to move away from the protector
concept for these kinds of checks.

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.

The two refactorings are somewhat orthogonal, but intersect at the
class and instance type list generation, which is why it's easier to
put them in one CL.
For the removal of HasIndexedField, the removal is motivated by the
fact that is no longer necessary, and that using a flag to store this
kind of information is hacky.
For the class list changes, this is a cleanup in that we no longer
generate third-order macros, but instead normal macro lists.
There is a functional change and bug-fix in that we no longer include
abstract classes in lists that refer to instance types or maps. It's
still somewhat broken though, so I can't test abstract internal classes
yet, though. Coming in a follow-up CL.

Bill kindly pointed out to me that v8windbg was not handling bit_field2
correctly. The issue was that the constexpr type for ElementsKind was,
somewhat unsurprisingly, "ElementsKind", but v8windbg expected a fully-
qualified type name like "v8::internal::ElementsKind". This change
addresses the problem in two ways:
1. Update v8windbg's type resolution logic to resolve type names as if
they were used in the v8::internal namespace. This makes it more
consistent with how those type names are used in other generated
Torque code, reducing surprises and the number of times we have to
write `v8::internal::` in .tq files.
2. Add compile-time verification that any constexpr type name used as a
string in class-debug-readers-tq.cc can also resolve as a type name.
