[BPF] add target feature allows-misaligned-mem-access This PR adds the allows-misaligned-mem-access target feature to the BPF target. The feature can enable misaligned memory access support in the LLVM backend, aligning Rust’s BPF target behavior with the corresponding LLVM update introduced in [llvm/llvm-project#167013](https://github.com/llvm/llvm-project/pull/167013) (included in LLVM 22).
The codegen crate contains the code to convert from MIR into LLVM IR,
and then from LLVM IR into machine code. In general it contains code
that runs towards the end of the compilation process.
For more information about how codegen works, see the rustc dev guide.
