When CONFIG_ARC_USE_UNALIGNED_MEM_ACCESS=y, we also
need to add -Xunaligned option for mdb to enable unaligned
memory access feature for nsim.

Switch nSIM from custom ARC UART to ns16550 model. That will
allow us to use zephyr images built for nSIM on other platforms
like HAPS, QEMU, etc...
This patch do:
* switch nSIM board to ns16550 UART usage
* change nSIM simulator configuration to use ns16550 UART model
* drop checks for CONFIG_UART_NSIM in ARC code
* update nSIM documentation

* current supported boards:
* emsk, iotdk, nsim, emsdp, hsdk.
* for the unsupported future boards, pls take a
reference of supported boards' board.cmake.
* mdb runner is required and the default runner for SMP
case, e.g., HSDK and nsim_hs_smp.
* other ARC boards can also choose to use mdb by
setting runner as mdb, e.g. west flash --runner mdb.
* with mdb runner, user can make a debug through mdb gui
* with arc_nsim or opencod runner (default runner), user
can make a debug through gdb cmdline.
