GC flags are now part of the {Heap} and should be respected by all
sub-components.

Also add a infrastructure to write tests accessing private methods.

We currently have several ways to share symbols that are used in
both native scripts and the runtime. This change unifies this.
We do not use the symbols registry since we don't need the
registry any longer after bootstrapping, but the registry stays
alive afterwards.

This CL us a pure refactoring that makes an empty compilation unit
including just "snapshot.h" but not "objects-inl.h" compile without
warnings or errors. This is needed to further reduce the header
dependency tangle.

This make inclusion of unicode-inl.h in object.h absolete. Now most
compilation units don't require that header. It also breaks a cycle
within declarations of the scanner.h header.

This tries to remove includes of "-inl.h" headers from normal ".h"
headers, thereby reducing the chance of any cyclic dependencies and
decreasing the average size of our compilation units.

Note that this change still leaves 3 violations of that rule in the
code, checked with the "tools/check-inline-includes.sh" tool.

Embedders would use these for features which must be able to be turned
off at runtime, despite being compiled into V8. They can be turned on
and off by the embedder using the --experimental_extras flag, e.g. via
v8::SetFlagsFromString.

JSObject::UnregisterPrototypeUser relies on the index of the weak
fixed array entry not to change.

See commit 1e65e201.

There is no bug currently, because we would only re-allocate if there is no empty slot left. In which case there is no actual compaction going on during re-allocation.
