Currently, the open-source builds of wamrc set WASM_ENABLE_DUMP_CALL_STACK,
which causes these two fields to be emitted. They are required by aot_emit_exception.c.
Internally at Google, we don't enable call stack dumps, so we've been using the
attached patch to make sure the fields are emitted anyway.
Add no_resolve to LoadArgs and wasm_runtime_resolve_symbols so one can
delay resolving of symbols.
This is useful for inspecting the module between loading and instantiating.
Enable dynamic aot debug feature which debugs the aot file
and is able to set the break point and do single step. Refer to
the README for the detailed steps.

This was originally fixed in #3655, but regressed in #3762 which removed
the `-fvisibility=hidden` flag from the CMakeLists.txt file.
This also removes extraneous ending whitespace from the file.
Now that WAMR supports multiple memory instances, this PR adds some APIs
to access them in a standard way.
This involves moving some existing utility functions out from the
`WASM_ENABLE_MULTI_MODULE` blocks they were nested in, but multi-memory
and multi-module seem independent as far as I can tell so I assume that's okay.
APIs added:
```C
wasm_runtime_lookup_memory
wasm_runtime_get_default_memory
wasm_runtime_get_memory
wasm_memory_get_cur_page_count
wasm_memory_get_max_page_count
wasm_memory_get_bytes_per_page
wasm_memory_get_shared
wasm_memory_get_base_address
wasm_memory_enlarge
```
I'm not sure we want to use C99 %tu here.
While C99 %zu is more widely used in WAMR, %tu is rare (if any)
and I'm not sure if it's ubiquitously implemented in platforms
we support.
- Implement TINY / STANDARD frame modes - tiny mode is only able to keep track on the IP
and func idx, STANDARD mode provides more capabilities (parameters, stack pointer etc.).
- Implement FRAME_PER_FUNCTION / FRAME_PER_CALL modes - frame per function adds
code at the beginning and at the end of each function for allocating / deallocating stack frame,
whereas in per-call mode the frame is allocated before each call. The exception is call to
the imported function, where frame-per-function mode also allocates the stack before the
`call` instruction (as it can't instrument the imported function).
At the moment TINY + FRAME_PER_FUNCTION is automatically enabled in case GC and perf
profiling are disabled and `values` call stack feature is not requested. In all the other cases
STANDARD + FRAME_PER_CALL is used.
STANDARD + FRAME_PER_FUNCTION and TINY + FRAME_PER_CALL are currently not
implemented but possible, and might be enabled in the future.

- Only retry on EAGAIN, ENOMEM or EINTR.
- On EINTR, don't count it against the retry budget, just keep retrying.
EINTR can happen in bursts.
- Log the errno on failure, and don't conditionalize that logging on
BH_ENABLE_TRACE_MMAP. In other parts of the code, error logging is not
conditional on that define, while turning on that tracing define makes
things overly verbose.
Mac on aarch64 uses posix_memmap.c os_mmap which doesn't do anything with
the flag MMAP_MAP_32BIT for that build so this condition ends up asserting unless
the mapping ends up in the first 4 gigs worth of addressable space.
Thsi PR changes to call os_mmap with MMAP_MAP_32BIT flag only when the target
is x86-64 or riscv64, and the macro __APPLE__ isn't enabled. The behavior is similar
to what the posix os_mmap does.
In the AOT compiler, allow the user to control stack boundary check when the boundary
check is enabled (e.g. `wamrc --bounds-checks=1`). Now the code logic is:
1. When `--stack-bounds-checks` is not set, it will be the same value as `--bounds-checks`.
2. When `--stack-bounds-checks` is set, it will be the option value no matter what the
status of `--bounds-checks` is.
