Merge dev/simd for fast-interp (#4131) 
* Implement the first few SIMD opcodes for fast interpreter (v128.const, v128.any_true) (#3818)

Tested on the following code:
```
(module
  (import "wasi_snapshot_preview1" "proc_exit" (func $proc_exit (param i32)))
  (memory (export "memory") 1)

  ;; WASI entry point
  (func $main (export "_start")
    v128.const i8x16 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
    v128.any_true
    if
      unreachable
    end
    
    v128.const i8x16 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15     
    v128.any_true
    i32.const 0
    i32.eq
    if
      unreachable
    end

    i32.const 0
    call $proc_exit
  )
)
```

* implement POP_V128()

This is to simplify the simd implementation for fast interpreter

* Add all SIMD operations into wasm_interp_fast switch

* Add V128 comparison operations

Tested using
```

/* Reserved bytes to the native thread stack boundary, throw native
* stack overflow exception if the guard boundary is reached
*
* WASM_STACK_GUARD_SIZE needs to be large enough for:
*
* - native functions
*
* w/o hw bound check, the overhead (aot_call_function etc) + the native
* function itself. as of writing this, the former is about 1000 bytes
* on macOS amd64.
*
* with hw bound check, theoretically, only needs to cover the logic to
* set up the jmp_buf stack.
*
* - aot runtime functions
* eg. aot_enlarge_memory.
*
* - w/o hw bound check, the interpreter loop
*
* the stack consumption heavily depends on compiler settings,
* especially for huge functions like the classic interpreter's
* wasm_interp_call_func_bytecode:
*
* 200 bytes (release build, macOS/amd64)
* 2600 bytes (debug build, macOS/amd64)
*
* - platform-provided functions (eg. libc)
*
* the following are examples of the stack consumptions observed for
* host APIs.
*
* snprintf: (used by eg. wasm_runtime_set_exception)
* - about 1600 bytes on macOS/amd64
* - about 2000 bytes on Ubuntu amd64 20.04
*
* gethostbyname:
* - 3KB-6KB on macOS/amd64
* - 10KB on Ubuntu amd64 20.04
*
* getaddrinfo:
* - 4KB-17KB on macOS/amd64
* - 12KB on Ubuntu amd64 20.04
* - 0.3-1.5KB on NuttX/esp32s3
*
* - stack check wrapper functions generated by the aot compiler
* (--stack-bounds-checks=1)
*
* wamrc issues a warning
* "precheck functions themselves consume relatively large amount of stack"
* when it detects wrapper functions requiring more than 1KB.
*
* - the ABI-defined red zone. eg. 128 bytes for SYSV x86-64 ABI.
* cf. https://en.wikipedia.org/wiki/Red_zone_(computing)
*
* Note: on platforms with lazy function binding, don't forget to consider
* the symbol resolution overhead on the first call. For example,
* on Ubuntu amd64 20.04, it seems to consume about 1500 bytes.
* For some reasons, macOS amd64 12.7.4 seems to resolve symbols eagerly.
* (Observed with a binary with traditional non-chained fixups.)
* The latest macOS seems to apply chained fixups in kernel on page-in time.
* (thus it wouldn't consume userland stack.)
