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
```
(module
  (import "wasi_snapshot_preview1" "proc_exit" (func $proc_exit (param i32)))

  (memory (export "memory") 1)

  (func $assert_true (param v128)

    v128.any_true
    i32.eqz
