This allows users to skip creation of `BufferSlice` if they have no use for it, and brings `wgpu` closer to the WebGPU API without removing any Rust convenience. New functions: * `BufferSlice::slice()` * `Buffer::map_async()` * `Buffer::get_mapped_range()` * `Buffer::get_mapped_range_mut()` * `Buffer::get_mapped_range()`
