[Kotlin]: Add a KotlinRecord concept, factor struct conversion with it

In the Dawn code generators, both structures and methods are considered
"records" that have a bunch of named parameter/members with types. The
conversion of structures and method records from Kotlin to C++ are very
similar. To merge them both, a KotlinRecord concept is added that is a
C++ structure for a the JNI objects representing the values of the
Kotlin records.

A macro is added that creates the KotlinRecord structure for a record
(either a structure, or a method).

A macro is added that creates a conversion function from a KotlinRecord
to a structure.

These two macros are used to factor out all of the common logic out of
structures.cpp. The logic in methods.cpp will be factored out in a
follow-up CL.

A few new primitive types are added to dawn_kotlin.json.

Helper CallGetter functions are added in structures.cpp to call the
correct JNIEnv::Call*Method depending on what return type we expect.

A couple hacks for handling the jlong ANativeWindow are added. We should
remove them with a manually written method.

Dawn, a WebGPU implementation

Dawn is an open-source and cross-platform implementation of the WebGPU standard. More precisely it implements webgpu.h that is a one-to-one mapping with the WebGPU IDL. Dawn is meant to be integrated as part of a larger system and is the underlying implementation of WebGPU in Chromium.

Dawn provides several WebGPU building blocks:

  • WebGPU C/C++ headers that applications and other building blocks use.
    • The webgpu.h version that Dawn implements.
    • A C++ wrapper for the webgpu.h.
  • A “native” implementation of WebGPU using platforms' GPU APIs: D3D12, Metal, Vulkan and OpenGL. See per API support for more details.
  • A client-server implementation of WebGPU for applications that are in a sandbox without access to native drivers
  • Tint is a compiler for the WebGPU Shader Language (WGSL) that can be used in standalone to convert shaders from and to WGSL.
