Since the top-level CMakelists.txt is appending `-fvisibility=hidden` to
the compile options, no public symbols are exported by default. This
forbids users from linking against the shared library.
Using `gcc/clang` attributes [1], it is possible to override the definition
for `WASM_RUNTIME_API_EXTERN` so that only required symbols are
correctly exported.

- Clear some compile warnings
- Fix some typos
- Fix llvm LICENSE link error
- Remove unused aot file and binarydump bin
- Add checks when loading AOT exports
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.
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
```
- 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.

- Add declarations related to emitting AOT files into a separate header file
named `aot_emit_aot_file.h`
- Add API `aot_emit_aot_file_buf_ex` and refactor `aot_emit_aot_file_buf` to call it
- Expose some APIs in aot_export.h
Support to get `wasm_memory_type_t memory_type` from API
`wasm_runtime_get_import_type` and `wasm_runtime_get_export_type`,
and then get shared flag, initial page cout, maximum page count
from the memory_type:
```C
bool
wasm_memory_type_get_shared(const wasm_memory_type_t memory_type);
uint32_t
wasm_memory_type_get_init_page_count(const wasm_memory_type_t memory_type);
uint32_t
wasm_memory_type_get_max_page_count(const wasm_memory_type_t memory_type);
```
Add flag `LoadArgs.clone_wasm_binary` to control whether to clone the wasm/aot
binary in wasm-c-api module. If false, API `wasm_module_new_ex` won't clone the
binary, which may reduce the footprint.
Add flag `LoadArgs.wasm_binary_freeable` to control whether the wasm/aot binary
may be freed after instantiation for wamr API `wasm_runtime_load_ex`, if yes, then
for some running modes, the wasm/aot module doesn't refer to the input binary
again so developer can free it after instantiation to reduce the footprint.
And add API `wasm_module_is_underlying_binary_freeable` and
`wasm_runtime_is_underlying_binary_freeable` to check whether the input binary
can be freed after instantiation for wasm-c-api and wamr api.
And add sample to illustrate it.
Support getting global type from `wasm_runtime_get_import_type` and
`wasm_runtime_get_export_type`, and add two APIs:
```C
wasm_valkind_t
wasm_global_type_get_valkind(const wasm_global_type_t global_type);
bool
wasm_global_type_get_mutable(const wasm_global_type_t global_type);
```
- Add a few API (https://github.com/bytecodealliance/wasm-micro-runtime/issues/3325)
```c
wasm_runtime_detect_native_stack_overflow_size
wasm_runtime_detect_native_stack_overflow
```
- Adapt the runtime to use them
- Adapt samples/native-stack-overflow to use them
- Add a few missing overflow checks in the interpreters
- Build and run the sample on the CI
