(RFC) Remove schema validation in `createBuffer`

[iwoplaza]

I think we should remove schema validation in createBuffer. Reasons:

• Logic could be moved into a type-aware lint plugin
• Prevents users from creating helper functions that accept generic types

Example of a generic function that fails

import { type TgpuRoot } from 'typegpu';
import { arrayOf } from 'typegpu/data';

export function createInstanceBuffer<StructData extends d.WgslStruct>(
  root: TgpuRoot,
  struct: StructData,
  length: number,
) {
  const instanceBuffer = root
    // ❌ `d.WgslArray<StructData> is not assignable to `ValidateBufferSchema<d.WgslArray<StructData>>`
    .createBuffer(d.arrayOf(struct, length))
    // ❌ A very long error relating to usages
    .$usage('vertex', 'storage');

  const instanceLayout = tgpu.vertexLayout(
    (n) => arrayOf(struct, n),
    'instance',
  );
  return [instanceBuffer, instanceLayout] as const;
}
