Add BPF_CORE_READ_USER(), BPF_CORE_READ_USER_STR() and their _INTO() variations to allow reading CO-RE-relocatable kernel data structures from the user-space. One of such cases is reading input arguments of syscalls, while reaping the benefits of CO-RE relocations w.r.t. handling 32/64 bit conversions and handling missing/new fields in UAPI data structs.
