rev 52749 : Bootstrap method consolidation
* clean up and simplify JDK support code for BSM invocation
* simplify JVM bootstrap handshake: use BootstrapCallInfo only
* remove unused JVM paths and data fields
* move bootstrap argument processing from MethodHandleNatives to ConstantPool
* remove ConstantGroup; merge argument access into BootstrapCallInfo
* adjust BSM argument access: remove copyArguments, add argumentRef API
* add metadata-free BSM modes, including symbolic arguments from CP
