wgpu::backend::web::Context::queue_validate_write_buffer is unimplemented

[jimblandy]

The body of the implementation of wgpu::Context::queue_validate_write_buffer for web::Context is a "TODO" comment. Presumably the underlying web APIs will do the validation anyway, but it would make wgpu present errors more consistently if we did implement this.

(This is no surprise to anyone, but I generally feel that "TODO" comments should be avoided in favor of issues, since our tools for tracking the latter are much better.)

I think this was blocked by web_sys not exposing buffer size and usage.
