bpf: add kfuncs and helpers support for file dynptrs
Add support for file dynptr.
Introduce struct bpf_dynptr_file_impl to hold internal state for file
dynptrs, with 64-bit size and offset support.
Introduce lifecycle management kfuncs:
- bpf_dynptr_from_file() for initialization
- bpf_dynptr_file_discard() for destruction
Extend existing helpers to support file dynptrs in:
- bpf_dynptr_read()
- bpf_dynptr_slice()
Write helpers (bpf_dynptr_write() and bpf_dynptr_data()) are not
modified, as file dynptr is read-only.
