DEX Version 38 added:
* CallSiteId & CallSite items

* Adds MethodHandleTo{MethodId, FieldId}
* Adds CodeToProtoId16 for invoke-polymorphic
* Adds CodeToCallSiteId16 and WriteCallSiteId16 for invoke-custom
* Updates CodeToMethodId16 for invoke-polymorphic

Fuzzed about 1 million iterations locally and uploaded new samples to
the clusterfuzz bucket. 97% coverage.

Manually tested on hand-written dex files using smali as well as the
dexdump test corpus.
