Add support for the [Zephyr Usermode](https://docs.zephyrproject.org/latest/kernel/usermode/index.html)
to the Zephyr port.
The following changes are applied:
- Fix `signbit`, check if it is defined already and only implement it, if not
- Introduce `sys_mutex` and `sys_sem` in favour of `k_mutex` and `k_sem`, when `CONFIG_USERMODE` is enabled
- Remove the installation of the `_stdout_hook_iwasm()` when `CONFIG_USERMODE` is enabled, otherwise this
causes MPU errors since the std hook is in the kernel space
- Add a thread name for debugging
For use with WAMR_BUILD_LIB_PTHREAD, add os_thread_detach,
os_thread_exit, os_cond_broadcast.

Use math functions only with `CONFIG_MINIMAL_LIBC=y`.
`CONFIG_PICOLIBC=y` or `CONFIG_NEWLIB_LIBC=y` provides math functions
that are used by wasm, and compilation fails when they are selected.

When running AOT code in Zephyr on STM32H743VIT6 without
CONFIG_CACHE_MANAGEMENT=y, a hard fault occurs, which leads to
SCB_CleanDCache().
It’s better to use the functions built into Zephyr.
Enhance the statistic of wasm function execution time, or the performance
profiling feature:
- Add os_time_thread_cputime_us() to get the cputime of a thread,
and use it to calculate the execution time of a wasm function
- Support the statistic of the children execution time of a function,
and dump it in wasm_runtime_dump_perf_profiling
- Expose two APIs:
wasm_runtime_sum_wasm_exec_time
wasm_runtime_get_wasm_func_exec_time
And rename os_time_get_boot_microsecond to os_time_get_boot_us.
Add an extra argument `os_file_handle file` for `os_mmap` to support
mapping file from a file fd, and remove `os_get_invalid_handle` from
`posix_file.c` and `win_file.c`, instead, add it in the `platform_internal.h`
files to remove the dependency on libc-wasi.

To allow non-POSIX platforms such as Windows to support WASI libc
filesystem functionality, create a set of wrapper functions which provide a
platform-agnostic interface to interact with the host filesystem. For now,
the Windows implementation is stubbed but this will be implemented
properly in a future PR. There are no functional changes in this change,
just a reorganization of code to move any direct POSIX references out of
posix.c in the libc implementation into posix_file.c under the shared
POSIX sources.
See https://github.com/bytecodealliance/wasm-micro-runtime/issues/2495 for a
more detailed overview of the plan to port the WASI libc filesystem to Windows.
And enable classic interpreter instead fast interpreter when llvm jit is enabled,
so as to fix the issue that llvm jit cannot handle opcode drop_64/select_64.
Implement XIP (Execution In Place) feature for AOT mode to enable running the AOT code inside AOT file directly, without memory mapping the executable memory for AOT code and applying relocations for text section. Developer can use wamrc with "--enable-indirect-mode --disable-llvm-intrinsics" flags to generate the AOT file and run iwasm with "--xip" flag. Known issues: there might still be some relocations in the text section which access the ".rodata" like sections.
And also enable ARC target support for both interpreter mode and AOT mode.

Fix sample littlevgl/guil build issues on zephyr platform, modify code of zephyr platform by adding some macros to control some apis to fit different zephyr version, and align to zephyr-v2.3.0 for sample littlevgl/gui as the latest zephyr version (>=v2.4.0) requires that the thread stack for the thread to create must be defined by macro but not allocating stack memory dynamically.
