Align v128 text format with WABT (#1930)
This PR changes the formatting of v128.const literals in text format / stack ir like so
- v128.const i32 0x1 0x2 0x3 0x4 0x5 0x6 0x7 0x8 0x9 0xa 0xb 0xc 0xd 0xe 0xf 0x80
+ v128.const i32 0x04030201 0x08070605 0x0c0b0a09 0x800f0e0d
Recently hit this when trying to load Binaryen generated text format with WABT, which errored with `error: unexpected token 0x5, expected ).
