Add more standard structural redefinition entrypoints
Add structural redefinition extension function and event that mirror
the 'RedefineClasses' function and 'ClassFileLoadHook' event. The new
extension function is called
'com.android.art.class.structurally_redefine_classes' and the new
extension event is called
'com.android.art.class.structural_dex_file_load_hook'.
These extensions are the preferred way to use structural redefinition.
Like the standard 'RedefineClasses' multiple classes may be redefined
at a time.
The structural_dex_file_load_hook is triggered prior to the
can_retransform_classes ClassFileLoadHook. It is triggered on all
classes, even ones that cannot be structurally changed by
class-loading, class redefinition or by calling the RetransformClasses
function.
Calling 'structurally_redefine_classes' with new definitions that do
not require structural changes will fall back to non-structural
redefinition.
