Auto merge of #110822 - scottmcm:lower-offset-to-mir, r=compiler-errors

Lower `intrinsics::offset` to `mir::BinOp::Offset`

They're [semantically the same](https://doc.rust-lang.org/nightly/nightly-rustc/rustc_middle/mir/enum.Rvalue.html#variant.BinaryOp), so this means the backends don't need to handle the intrinsic and means fewer MIR basic blocks in pointer arithmetic code.
