This is a follow-up of JDK-8226916. Lookup::hasPrivateAccess intends to
test if this lookup is a full-power lookup; that is created by the
original caller class calling MethodHandles::lookup. The current
specification for Lookup::hasPrivateAccess returns true if the lookup
modes contain PRIVATE but it does not check MODULE bit.
This patch also clarifies the capabilities w.r.t PRIVATE access and
full-power access. The security permission check is performed if the
Lookup is not a full power lookup and therefore Lookup::defineClass spec
should be updated to perform security permission check if the security
manager is present and this lookup refuses access, consistent with other
Lookup operations.
