Add more types for attr_container, e.g. uint8, uint32, uint64
Add more APIs for attr_container for int8, int16 and int32 types
Rename fields of the union 'jvalue' and refactor some files that use attr_container
This syscall doesn't need allocating stack or TLS and it's expected from the application
to do that instead. E.g. WASI-libc already does this for `pthread_create`.
Also fix some of the examples to allocate memory for stack and not use stack before
the stack pointer is set to a correct value.
Because stack grows from high address towards low address, the value
returned by malloc is the end of the stack, not top of the stack. The top
of the stack is the end of the allocated space (i.e. address returned by
malloc + cluster size).
Refer to #1790.
The original CI didn't actually run wasi test suite for x86-32 since the `TEST_ON_X86_32=true`
isn't written into $GITHUB_ENV.
And refine the error output when failed to link import global.
Add thread_wait_list_end node for thread data and cond for Windows platform
to speedup the thread join and cond wait operations: no need to traverse the
wait list to get the end node to append the wait node.
According to the [WASI thread specification](https://github.com/WebAssembly/wasi-threads/pull/16),
some thread identifiers are reserved and should not be used. In fact, only IDs between `1` and
`0x1FFFFFFF` are valid.
The thread ID allocator has been moved to a separate class to avoid polluting the
`lib_wasi_threads_wrapper` logic.
Should use import_function_count but not import_count to calculate
the func_index in handle_name_section when custom name section
feature is enabled.
And clear the compile warnings of mini loader.
Support modes:
- run a commander module only
- run a reactor module only
- run a commander module and a/multiple reactor modules together
commander propagates WASIArguments to reactors
Implement 2-level Multi-tier JIT engine: tier-up from Fast JIT to LLVM JIT to
get quick cold startup by Fast JIT and better performance by gradually
switching to LLVM JIT when the LLVM JIT functions are compiled by the
backend threads.

Allow to add watchpoints to variables for source debugging. For instance:
`breakpoint set variable var`
will pause WAMR execution when the address at var is written to.
Can also set read/write watchpoints by passing r/w flags. This will pause
execution when the address at var is read:
`watchpoint set variable -w read var`
Add two linked lists for read/write watchpoints. When the debug message
handler receives a watchpoint request, it adds/removes to one/both of these
lists. In the interpreter, when an address is read or stored to, check whether
the address is in these lists. If so, throw a sigtrap and suspend the process.
When a wasm module is duplicated instantiated with wasm_instance_new,
the function import info of the previous instantiation may be overwritten by
the later instantiation, which may cause unexpected behavior.
Store the function import info into the module instance to fix the issue.
This PR allows reusing thread ids once they are released. That is done by using
a stack data structure to keep track of the used ids.
When a thread is created, it takes an available identifier from the stack. When
the thread exits, it returns the id to the stack of available identifiers.

For now this implementation uses thread manager.
Not sure whether thread manager is needed in that case. In the future there'll be likely another syscall added (for pthread_exit) and for that we might need some kind of thread management - with that in mind, we keep thread manager for now and will refactor this later if needed.
