nfp: bpf: complete ALU32 logic shift supports
The following ALU32 logic shift supports are missing: BPF_ALU | BPF_LSH | BPF_X BPF_ALU | BPF_RSH | BPF_X BPF_ALU | BPF_RSH | BPF_K For BPF_RSH | BPF_K, it could be implemented using NFP direct shift instruction. For the other BPF_X shifts, NFP indirect shifts sequences need to be used. Separate code-gen hook is assigned to each instruction to make the implementation clear.
