Various small changes are required to enable this. HeapObject::GetReadOnlyRoots no longer uses the Space's heap when possible (see comment in ReadOnlyHeap::GetReadOnlyRoots definition). This requires that ReadOnlyRoots be construct-able using a raw pointer to the read-only space's roots array. Global read-only heap state is now cleared by tests where appropriate and extra DCHECKs in ReadOnlyHeap::SetUp should make catching future issues easier. String padding is now always cleared just before read-only space is sealed when not deserializing.

This takes heap-inl.h out of the "Giant Include Cluster". Naturally, that means adding a bunch of explicit includes in a bunch of places that relied on transitively including them before. As of this patch, no header file outside src/heap/ includes heap-inl.h.

Change Heap::IterateStrongRoots to never iterate the read-only roots. In doing so remove VISIT_ALL_BUT_READ_ONLY and VISIT_ONLY_STRONG_FOR_SERIALIZATION. All such uses should now use VISIT_ALL and VISIT_ONLY_STRONG. Where ReadOnlyRoots iteration is required, this adds ReadOnlyRoots(isolate)->Iterate() at the call site. Add new begin, end, strong_mutable_roots_begin and strong_mutable_roots_end methods to RootsTable and try and make the existing uses a little more consistent.

... and Heap::root_handle() to RootsTable. This is a preliminary step before moving IsolateData object from Heap to Isolate which is required for pointer-compression friendly heap layout.
