Adapt the macOS AVFoundation backend for multi-device discovery,
camera index mapping and capture startup compatibility. This enables
reliable use of multiple cameras through the SIM camera framework.

Allow the SIM camera/V4L2 capture framework to manage multiple
imgdata instances with dynamic mounting. This avoids cross-talk
between camera streams when multiple devices are used.

Add CONFIG_SIM_WALLTIME_RATIO Kconfig option and --sim-rt-ratio=
command-line argument to control the ratio of simulated time to
real time in percent. 100 means real-time (default), 200 means
simulated time advances twice as fast, 50 means half speed.
The implementation applies the ratio in host_gettime(), host_sleepuntil()
and host_settimer() so both SIM_WALLTIME_SLEEP and SIM_WALLTIME_SIGNAL
modes are supported.
This is inspired by the --rt-ratio feature in Zephyr's native_sim board.
Tested on sim:nsh with the following sleep test:
$ echo -e "sleep 2\nexit" | time ./nuttx
real 0m2.0xxs
$ echo -e "sleep 2\nexit" | time ./nuttx --sim-rt-ratio=200
real 0m1.0xxs
$ echo -e "sleep 2\nexit" | time ./nuttx --sim-rt-ratio=50
real 0m4.0xxs

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.
