Copy JvmDescriptorUtils and KotlinMetadata utils

This is an almost 1-1 copy of JvmDescriptorUtils and kotlin metadata utils from
room:compiler to xprocessing.
Once room is migrated, they'll be deleted from Room.
Right now these classes are not used but they'll be used in a followup CL when I
add support for executable elements.
