  Log Message:
  -----------
  [CodeGen][CIR] Share AArch64/AMDGPU target predicates via CodeGenUtils

Classic CodeGen and CIR CodeGen each carry their own copy of three
AST-only target predicates:

  * the AArch64 SME inlinability cluster (the ArmSMEInlinability bitmask
    enum, its isStreamingCompatible helper, and GetArmSMEInlinability),
  * requiresAMDGPUProtectedVisibility, and
  * HasExtraNeonArgument.

None of them touch llvm::Type, llvm::Value or the CIR dialect, so move
them into a new clang/CodeGenUtils/TargetUtils.h and drop the
duplicates.  requiresAMDGPUProtectedVisibility now takes a bool for the
current visibility instead of a backend-specific global value, which is
all either caller actually inspected.

NFC.
