Map::HasOnlyStablePrototypesWithFastElements and
Map::SerializeForElementStore were asking if the prototype was a
JSObject but they were doing so with the original map on every loop
iteration instead of the current prototype's map.
Also, we can change it so that instead of using the underlying data
to check if it was a JSObject, but we can get the same information
reading the map's instance_type directly.

In https://crrev.com/c/2842128, a concern was raised that using
`V8InspectorSession::createCommandLineAPI` directly would not cache the command line
API definitions and V8 could expose a higher level API for this use
case. This CL exposes `InjectedScript::ContextScope` via V8InspectorSession.
If this approach is approved, V8InspectorSession::createCommandLineAPI
could be removed.

By (mostly) unifying the different kinds of WasmFunctionData, and
precomputing and caching what we can, we can reduce the amount of
work that has to be done for each call.
We still have to store the current instance for JS function calls;
that may be eliminatable in the future.
WasmCapiFunctions are not included in the refactoring yet.

The "Restart frame" feature was implemented as part of LiveEdit and
primarily used to support LiveEdit of active functions, but that was
previously disabled as part of https://crrev.com/c/2846892 because it's
too brittle and causes crashes when using seemingly unrelated features.
The "Restart frame" feature was also available as a context menu item
separately in the DevTools front-end, but that was also already removed
as part of https://crrev.com/c/2854681 earlier. So all uses are gone
now.
This change works by marking Debugger.restartFrame as deprecated and
having it respond with a ServerError all the time. It thus allows us to
remove a whole bunch of machinery that was essentially just put in
various places to support the restart_fp_ magic. In particular the
debugger no longer needs any machine specific builtins now.

While evaluating a class literal the containing function points to
Token::CLASS. It may have pushed a context for that class that uses
the range of the class scope. So far the class scope had a range that
started after the class name or class token in case of anonymous
classes. That means the source position of the function frame doesn't
point to a position that is included in the active context range. This
breaks the debugger because it relies on being able to find the
matching parser scope for the active context by looking at the source
position.
The fix is two-fold:
- extend the class scope source range to include Token::CLASS
- update ScopeChainRetriever::ContainsPosition to include the start
position of class scopes as a valid source position. We can't always
include start due to arrow functions that don't have braces.

This CL factors out a CodeRange class out of MemoryAllocator.
When V8_COMPRESS_POINTERS_IN_SHARED_CAGE is defined, there is a single
CodeRange shared by all Isolates in the process. This also turns short
builtins back for both configurations of pointer compression. When
sharing a cage, there is a single copy of the re-embedded builtins.
Since a shared pointer cage is still experimental, to avoid API churn
this CodeRange's size is not configurable and is always the maximal size
depending on the underlying platform.
