[AArch64][Clang] Update new Neon vector element types. (#142760)
This updates the element types used in the new __Int8x8_t types added in #126945, mostly to allow C++ name mangling in ItaniumMangling mangleAArch64VectorBase to work correctly. Char is replaced by SignedCharTy or UnsignedCharTy as required and Float16Ty is better using HalfTy to match the vector types. Same for Long types.
