[Zucchini] DEX Version 38 Support
DEX Version 38 added:
* CallSiteId & CallSite items
* MethodHandle items
* invoke-polymorphic containing meth@BBBB and proto@HHHH references
* invoke-custom containing a call_site@BBBB reference
This CL:
* Adds CallSiteIdToCallSite
* 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.
