Kevin Moore e0b028808a [dart2wasm] Expand Wasm SIMD intrinsics for vector operations 
Add more Wasm SIMD intrinsics and instructions to support efficient
vector operations, specifically targeting the requirements of types
like Offset and Size.

- Implement new intrinsics in `dart2wasm`:
  - `anyTrue` for V128.
  - `allTrue` for I64x2.
  - `pmin`/`pmax` (pseudo-minimum/maximum) for F64x2.
  - `fromLaneValues` for F32x4 and F64x2.
  - `shuffle` for F64x2.
- Update `wasm_builder` with support for the following instructions:
  - `v128.any_true`
  - `i8x16.all_true`, `i16x8.all_true`, `i32x4.all_true`, `i64x2.all_true`
  - `i8x16.shuffle` (including serialization and deserialization)
- Add `tests/web/wasm/simd/vector_test.dart`, which implements `Offset`
  and `Size` using these new SIMD intrinsics, demonstrating their
  practical utility and correctness.
- Update `tests/web/wasm/simd/simd_test.dart` with additional coverage.

Nate Biggs 5a02a7a019 [dart2wasm] SIMD instructions template 
SIMD proposal:
https://github.com/WebAssembly/spec/blob/main/proposals/simd/SIMD.md

This only implements a few of the available SIMD instructions as a
template for further contribution. kevmoo@ plans to continue
implementing these.
