Cross-bitness support in JitInterface (#18329)

Cross-bitness support in JitInterface (#18329)

* Replace sizeof(tailCallType) / sizeof(tailCallType[0]) with _countof(tailCallType)

* Remove TransparentProxyObject and RealProxyObject

* InlinedCallFrame::GetEEInfo should not be used for R2R compilation

* Hardcode constants used in CEEInfo::getEEInfo

* Thread fields should not be used for R2R compilation

* Zero pEEInfoOut->inlinedCallFrameInfo when compiling R2R code

* Rename OFFSETOF__PtrArray__m_Array to avoid compilation conflicts with asmconstants

* Add assertions enabled in every non-crossbitness scenario

* Define and use CROSSBITNESS_COMPILE macro
