zephyr: Enable WASI support for file system and sockets on zephyr (#3633)
This work also implements the WASI support on Zephyr.
* Added os_is_* methods for stdin/stdout/stderr. Fixed issues in os_renameat
* Zephyr platform fixes for WASI sockets Addressed numerous of build warnings on Zephyr
* Updated `os_writev` to use `fwrite` for STDOUT/STDERR
* Temporarily reverted change to `writev` to work around an issue.
* Fixes: fstat, fstatat, and unlink
* Add initial support for directories in os_openat. Partial implementation — just avoids a hard fault.
* Directory support WIP. readdir works but I think we have a memory leak somewhere
* Fix: always use standard stream fds. Fix unlinkat and renameat. fd 0, 1, and 2 will always be supplied for standard streams. Unlinkat and renameat work exclusively based on supplied paths.
* Fix: use macro for free()
* Added a temporary workaround for issue identified in PR#4377
* Fixed reference to file descriptor and cleaned up dead/commented code.
Note that some comments haven't been addressed and will be fixed in the
further patches.

* initialize WASI stdio handles to invalid for better error handling
* implement os_invalid_raw_handle function for consistent invalid handle representation
The `os_mremap` and `os_getpagesize` were missing in the `core/shared/platform/riot`
and were preventing RIOT from compiling if using WAMR v2.x.x. This PR is adding
both functions and should allow RIOT to update WAMR version to v2.x.x.

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.
