Corentin Wallez 82fbccbd78 Introduce [Render|Compute]PassEncoder. 
This splits off part of CommandBufferBuilder in separate
RenderPassEncoder and ComputePassEncoder objects. To match the WebGPU
IDL and factor some code, both these encoders inherit from
ProgrammablePassEncoder.

These encoders are pure frontend objects and record into the
CommandBufferBuilder command allocator objects, so no changes to the
backends were needed.

Error handling is still ew, because the "builder" mechanism we had
doesn't allow for "split builders". Nicer error handling will have to
wait on Dawn matching WebGPU.

All the tests and samples were updated to the new structure.

Dawn glTF Viewer

This is a barebones glTF model viewer using the Dawn API. It is intended as a proof of concept for the API and is not a robust model viewer. It can load basic mesh/texture data from a few glTF sample models, such as:

  • 2CylinderEngine
  • BoxWithoutIndices
  • Cesium Man
  • Duck
  • Monster
  • VC (Virtual City)

Usage

build/examples/glTFViewer/glTFViewer path/to/Duck.gltf
