Initial implementation of generic dictionary access for R2R. (#4519)
For now, only TypeHandle dictionary entry slots are supported and encoded in a R2R version resilient format (the rest to come soon).
Support is only limited for x64 Windows platforms (rest is still TODO)
The basic idea: each dictionary access is initally a call to a DynamicHelper R2R cell that computes the dictionary signature, and patches the R2R cell address with an assembly stub that performs the dictionary lookup.
