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.

Use this instead of manually copying LR to PC. With GNU libunwind,
both registers are equal after unw_step.
With the LLVM libunwind (which Apple uses), the return address isn't
reflected at all in LR, only in UNW_REG_IP.
