core: ldelf: implement separate syscalls for ldelf

Implements a separate syscall handler for ldelf to decouple it from user
TAs and enable using it for all TSs. The calling convention is the same

core: ldelf: implement separate syscalls for ldelf

Implements a separate syscall handler for ldelf to decouple it from user
TAs and enable using it for all TSs. The calling convention is the same
as for utee_* syscalls. To distinguish between the different SVCs, the
syscall handler pointer is updated before entering ldelf and restored
after returning. The step of opening a system PTA session and invoking
the commands there is eliminated, the necessary functionality is
implemented in the ldelf syscall functions.
