Add CAN support for sim target based on host SocketCAN interface.
Tested with virtual CAN on Linux but should work also with hardware CAN cards supported by host.

1. CONFIG_ARCH_COVERAGE has been replaced by CONFIG_SCHED_GCOV
2. Delete the SIM-specific GCOV_ALL configuration and change it to a universal configuration for all architectures

The link script of NuttX Simulator is generated through compilation
options. This PR will support configure special data sections in
kconfig to meet the support of 3rd party applications.
we need to follow the syntax of linker script. In 3rd-party applications, some data will be labeled as section:
| a.c:
| struct task_s a __attribute__((section(".data.custom.taska")));
| b.c:
| struct task_s b __attribute__((section(".data.custom.taskb")));
Data of the same type struct can be placed in a fixed location to reduce the overhead caused by searching:
| .data :
| {
| _custom_data_table_start = .;
| KEEP(*(.data.custom.*))
| _custom_data_table_end = .;
| }
Such section declare can be configured via Kconfig in the PR:
| CONFIG_SIM_CUSTOM_DATA_SECTION=" .data : { _custom_data_table_start = .; KEEP(*(.data.custom.*)) _custom_data_table_end = .; } "

Add the Sim WiFi function, which can provide the wifi operating on nuttx sim emulator,
and support two modes that simulate wifi, HWSIM and RNC(real network card).
- In the HWSIM mode, we simulates two wlan interfaces. The wlan0 is STA and
the wlan1 is AP. The wlan0 can connect to the wlan1 in the nuttx simulator.
- In the RNC mode, we can use the same wlan interface name on the nuttx simulator
to control the connection behavior of the real wireless card.

Support more than one TAP device for debugging (future) NAT and FORWARD, left WPCAP and VPNKit unchanged (force number to 1).
Although we can support at most 31 interfaces, limit to 8 like CONFIG_TUN_NINTERFACES.
