Copy shared_libs and system_shared_libs to module snapshot 

This change ensures that the runtime dependencies between a
binary/shared library are correctly specified in the snapshot so that
the build can ensure that shared libraries are built before the targets
that use them.

It adds support for differentiating between references that are
required to refer to another sdk member (required) and those that may
refer to either an sdk member or a non-sdk member (optional). The
latter is used for shared library references as the libraries used by
an sdk member may be provided from outside the sdk. e.g. liblog is not
part of the ART module but is used by some members of the ART sdk.

// is correctly output for both versioned and unversioned prebuilts in the
// snapshot.
//
// "required: true" means that the property must only contain references
// to other members of the sdk. Passing a reference to a module that is not a
// member of the sdk will result in a build error.
//
// "required: false" means that the property can contain references to modules
// that are either members or not members of the sdk. If a reference is to a
// module that is a non member then the reference is left unchanged, i.e. it
// is not transformed as references to members are.
//
// The handling of the member names is dependent on whether it is an internal or
// exported member. An exported member is one whose name is specified in one of
// the member type specific properties. An internal member is one that is added
// due to being a part of an exported (or other internal) member and is not itself
// an exported member.
//
// Member names are handled as follows:
// * When creating the unversioned form of the module the name is left unchecked
// unless the member is internal in which case it is transformed into an sdk
// specific name, i.e. by prefixing with the sdk name.
//
// * When creating the versioned form of the module the name is transformed into
// a versioned sdk specific name, i.e. by prefixing with the sdk name and
// suffixing with the version.
//
// e.g.
// bpPropertySet.AddPropertyWithTag("libs", []string{"member1", "member2"}, builder.SdkMemberReferencePropertyTag())
