impr: Emit a suppressible warning when a schema that's not uniform-aligned is used in a uniform buffer

[iwoplaza]

const Params = d.struct({
  start: d.vec2f,
  end: d.vec2f,
});

// ⚠️ [unaligned-uniforms] Type `Params` was used in a uniform buffer, but isn't aligned to 16 bytes. This may cause issues on some devices.
const paramsUniform = root.createUniform(Params);

How to suppress:

const root = await tgpu.init({
  suppress: {
    // false by default
    'unaligned-uniforms': true,
  },
});

Nice!
Do we assume that library creators will always obey this alignment requirement?

I think it's safe to assume that. This warning will appear in their test apps, and we should make it clear in the warning that not adhering to alignment is not portable.

If they want to align only when the hardware doesn't support it in a transparent way, then they can query the capabilities internally
