Use LLVM new pass manager for wamrc to replace the legacy pass manger,
so as to gain better performance and reduce the compilation time.
Reference links:
- https://llvm.org/docs/NewPassManager.html
- https://blog.llvm.org/posts/2021-03-26-the-new-pass-manager
And add an option to use the legacy pm mode when building wamrc:
cmake .. -DWAMR_BUILD_LLVM_LEGACY_PM=1
For JIT mode, keep it unchanged as it only runs several function passes and
using new pass manager will increase the compilation time.
And refactor the codes of applying LLVM passes.
Refactor LLVM Orc JIT to actually enable the lazy compilation and speedup
the launching process:
https://llvm.org/docs/ORCv2.html#laziness
Main modifications:
- Create LLVM module for each wasm function, wrap it with thread safe module
so that the modules can be compiled parallelly
- Lookup function from aot module instance's func_ptrs but not directly call the
function to decouple the module relationship
- Compile the function when it is first called and hasn't been compiled
- Create threads to pre-compile the WASM functions parallelly when loading
- Set Lazy JIT as default, update document and build/test scripts
Currently when calling wasm_runtime_call_wasm() to invoke wasm function
with externref type argument from runtime embedder, developer needs to
use wasm_externref_obj2ref() to convert externref obj into an internal ref
index firstly, which is not convenient to developer.
To align with GC feature in which all the references passed to
wasm_runtime_call_wasm() can be object pointers directly, we change the
interface of wasm_runtime_call_wasm() to allow to pass object pointer
directly for the externref argument, and refactor the related codes, update
the related samples and the document.
Allow empty import array (but not NULL) for wasm-c-api wasm_instance_new,
which makes the code more robust, especially in use cases where imports
might be constructed dynamically.
And add a test case in samples/wasm-c-api/src/empty_imports.c to test it.
Apply clang-format for core/iwasm/include, core/iwasm/common and
core/iwasm/aot files.
Update spec cases test script:
- Checkout latest commit of https://github.com/WebAssembly/spec
- Checkout main branch but not master of https://github.com/WebAssembly/threads
- Update wabt to latest version
And update source debugging document.

Fix document issues: add ARC to supported targets, fix how to build wamrc for MacOS.
Fix spec case test script issue: the latest wabt has enabled simd by default, no need to
add "--enable-simd" option for test script.
Fix simd LLVM IR compilation issue: using index calculated by opcode to access array
element should not be out of array boundary, add bh_assert() for it.

The WASM C API now requires the use of vector types in certain apis.
Switching WAMR to use the new call signatures improves "drop in"
compilation compatibility between WAMR and other implementations
from a C-api embedding program's perspective.
* wasm_func_callback_t type has been updated to use wasm_val_vec_t
* wasm_func_callback_with_env_t type has been updated to use wasm_val_vec_t
* wasm_func_call() has been updated to use wasm_val_vec_t
* wasm_instance_new() has been updated to use wasm_extern_vec_t*
* wasm_instance_new_with_args() has been updated to use wasm_extern_vec_t*
* wasm_runtime_invoke_c_api_native() has been updated to support vector types
in native callbacks without modifying the contract with the interpreter code.
* All users of the modified functions (including samples/wasm-c-api/src/*.c)
have been appropriately updated.
Enable to build wamrc with custom llvm, enable to auto detect processor on apple silicon, and fix some compile warnings.

Implement more wasm-c-api APIs to support Envoy integration:
- sync up with latest c-api definition
- change CMakeLists to export necessary headers and install the static library of iwasm
- enable to export tables and memories
- support memorytype and tabletype APIs
- update wasm-c-api sampels
- enable to export importtype APIs
And refine bazel scripts for sample XNNPACK workload, add license headers for sample simple.

In some platforms, allocating memory with size 0 may return NULL but not an empty memory block, which causes runtime load, instantiate or execute wasm/aot file failed. We add checks to try to avoid allocating memory in runtime if the size is 0. And in wasm_runtime_malloc/free, output warning if allocate memory with size 0 and free memory with NULL ptr.
Also fix some coding style issues, fix handle riscv32 ilp32d issue, and fix several wasm-c-api issues.
