[RFC] Unifying the use of accessors

[iwoplaza]

Since accessors are (at least currently) readonly, and the way to access the value within is to call them as a function, it would be nice to have a unified API in both WGSL strings and in TGSL.

const getFactor = tgpu.accessor(f32);

const alpha = tgpu.fn([]).does(() => {
  const factor = getFactor();
});

const beta = tgpu.fn([])
  .does(`() {
    // The injected WGSL can be either a function call, or just a reference to a resource
    let factor = getFactor;
  }`)
  .$uses({ getFactor });

The new behavior would require "calling" accessors in WGSL strings, even though the () after the accessor identifier will be erased.

const beta = tgpu.fn([])
  .does(`() {
    let factor = getFactor();
  }`)
  .$uses({ getFactor });

Agreed!

Makes sense to me
