fix: Repeat call in `d.mat4x4f.translation`

  it('...', () => {
    const myVar = tgpu.privateVar(d.u32);
    const helper = () => {
      'use gpu';
      myVar.$++;
      return myVar.$;
    };
    const main = () => {
      'use gpu';
      const t = d.mat4x4f.translation(d.vec3f(helper()));
    };

    expect(tgpu.resolve([main])).toMatchInlineSnapshot(`
      "var<private> myVar: u32;

      fn helper() -> u32 {
        myVar++;
        return myVar;
      }

      fn main() {
        let t = mat4x4f(1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1, 0, vec3f(f32(helper())).x, vec3f(f32(helper())).y, vec3f(f32(helper())).z, 1);
      }"
    `);
  });

Either delegate to another function, or find a way to detect this case and throw

Reproduce the issue with the provided test using d.mat4x4f.translation, helper(), and tgpu.resolve. Trace the implementation of d.mat4x4f.translation and the generated shader expression, then either delegate the repeated evaluation or reject this case; done means helper() is not emitted three times or the unsupported case throws clearly.
