ntdll: Preserve syscall frame when calling async IO system APC.
...
The frame can currently be reset from ws2_32.dll async IO callbacks
which are still in the user part and are calling 'syscall' functions.
If the user APC is processed after that during the same call to
server_select(), the call_user_apc_dispatcher() faults.

ntdll: Restore the original Lr value when unwinding through raise_func_trampoline on arm64.
...
When a signal is raised in a leaf function (that hasn't backed up
the Lr register itself), we need to restore both Pc and Lr separately.
This doesn't seem to be possible via libunwind, so add a special case
unwinding rule for this function.
As we have a special case for the function, we could also just as well
skip normal dwarf unwinding for this function altogether and just
restore the full context from the stack.
