Improvements to Field.get/set.

Avoid unnecessary repeated computation in Field.get/set.
Refactor FromReflectedField and FromReflectedMethod into common helpers in
mirror::ArtField and mirror::ArtMethod, and make use of thereby avoiding
transitions through JNI.
Avoid JNI use from within FromReflectedField and FromReflectedMethod.
Tidy up Field.get/set wrt moving collector support.
