[ORC-RT] Rename extensible_rtti.{h,cpp} to rtti.{h,cpp}. NFCI.

The "extensible_" prefix on these files was inherited from LLVM, where it
distinguished the dynamic RTTI APIs from the LLVM's custom static RTTI APIs.

In the ORC runtime these files will be used to hold all of our RTTI APIs
(the current dynamic ones, and any static ones added in the future), so we
shouldn't use this prefix.
