Deal with compilation warnings in JIT in cross-bitness scenario (#19590)

Deal with compilation warnings in JIT in cross-bitness scenario  (#19590)

* Fix warnings due to "strlen return type is size_t" in src/jit/emitarm.cpp src/jit/unwindarm.cpp

* Use ptrdiff_t disp in emitter::emitOutputInstr in src/jit/emitarm.cpp

* Compiler::gtHashValue should depend on host-bitness in src/jit/gentree.cpp

* Simplify checking using ImmedValNeedsReloc() in src/jit/lowerarmarch.cpp

* Use target_ssize_t immVal in Lowering::IsContainableImmed in src/jit/lowerarmarch.cpp

* Remove int offs and use BYTE* addr and %p specifier in emitter::emitDispInsHelp in IF_T2_J3 case in src/jit/emitarm.cpp

* Cast gtIconVal to target_size_t in CodeGen::genLclHeap in src/jit/codegenarm.cpp

* Use int argSize in CodeGen::genEmitCall in src/jit/codegen.h src/jit/codegenlinear.cpp

* Use ssize_t disp in emitter::emitIns_Call in src/jit/emitarm.cpp src/jit/emitarm.h

* Use int argSize in emitter::emitIns_Call in src/jit/emitarm.cpp src/jit/emitarm.h

* Use target_size_t return type in Compiler::eeGetPageSize Compiler::getVeryLargeFrameSize in src/jit/codegencommon.cpp src/jit/compiler.h

* Cast gtIconVal to unsigned in CodeGen::genCodeForShift CodeGen::genCodeForShiftLong in src/jit/codegenarm.cpp src/jit/codegenarmarch.cpp

* Cast gtIconVal to unsigned in DecomposeLongs::DecomposeRotate in src/jit/decomposelongs.cpp

* Use unsigned size in CodeGen::genConsumePutStructArgStk in src/jit/codegenlinear.cpp

* Use target_ssize_t stmImm in cast in CodeGen::genZeroInitFrame in src/jit/codegencommon.cpp

* Cast to target_ssize_t in Compiler::gtSetEvalOrder in src/jit/gentree.cpp

* Address PR feedbask - use dspPtr(addr) in src/jit/emitarm.cpp
