This commit adds a check to `fd_advise`. If the fd is a directory,
return `ebadf`. This brings iwasm in line with Wasmtime's behavior.
WASI folks have stated that fd_advise should not work on directories
as this is a Linux-specific behavior:

- Fix op_br_table arity type check when the dest block is loop block
- Fix op_drop issue when the stack is polymorphic and it is to drop
an ANY type value in the stack
* Empty names are spec-wise valid.
* As we ignore unknown custom sections anyway, it's safe to
accept empty names here.
* Currently, the problem is not exposed on our CI because
the wabt version used there is a bit old.
For shared memory, runtime should get the memories pointer from
module_inst first, then get memory instance from memories array,
and then get the fields of the memory instance.
Support new a wasm_config_t, set allocation and linux_perf_support
options to it, and then pass it to wasm_engine_new_with_config to
new an engine with private configuration.
Update the wabt release binary name for macos and fix a syntax error:
```bash
./test_wamr.sh: line 356: syntax error near unexpected token `;'
./test_wamr.sh: line 356: ` ;&'
```
Includes a number of updates to the Zephyr example, including removing a fair
amount of stale configuration. This is part of moving towards supporting WAMR
as a Zephyr module as described in #2782. Some functionality is removed as
part of this diff (e.g. AOT XTENSA support), but it had become stale while not
being actively maintained. It is anticipated that it (and AOT support for other
platforms) will be added back, along with CI support for ensuring they do not
become stale again.

The JSON evidence is allocated on the module instance heap, but no API
was given to dispose of this memory buffer. The sample mentions using
the function free, which behaves differently depending on the
execution context.
This fix provides a new function called librats_dispose_evidence_json,
enabling freeing the JSON evidence directly from the Wasm app.
Change WASMMemoryInstance's field is_shared_memory's type from bool
to uint8 whose size is fixed, so as to make WASMMemoryInstance's size
and layout fixed and not break AOT ABI.
See discussion in https://github.com/bytecodealliance/wasm-micro-runtime/pull/2682.
The popped reachable block may be if block whose else branch hasn't been
translated, and should push the params for the else block if there are.
And use LLVMDisposeMessage to free memory allocated in is_win_platform.
Currently, `data.drop` instruction is implemented by directly modifying the
underlying module. It breaks use cases where you have multiple instances
sharing a single loaded module. `elem.drop` has the same problem too.
This PR fixes the issue by keeping track of which data/elem segments have
been dropped by using bitmaps for each module instances separately, and
add a sample to demonstrate the issue and make the CI run it.
Also add a missing check of dropped elements to the fast-jit `table.init`.

CryptGenRandom is deprecated by Microsoft and may be removed in future
releases. They recommend to use the next generation API instead. See
https://learn.microsoft.com/en-us/windows/win32/seccng/cng-portal for
more details. Also, refactor the random functions to return error codes
rather than aborting the program if they fail.
