This didn't make sense since these members can be specified to have no
data by setting the length to 0.
- Prevent uses of this patten by adding an assert in WireCmd.cpp's
generator.
- Fix SetBindGroup dynamicOffset to not be optional but default to
nullptr instead.
This issues would cause a read of uninitialized pointers becaus the
generator code looked like this:
SetBindGroupCmd cmd;
cmd.dynamicOffsetCount = record.dynamicOffsetCount; // 1
bool has_dynamicOffset = record.has_dynamicOffsetl // false
if (has_dynamicOffset) {
cmd.dynamicOffsets = ...;
}
// Oh no! dynamicOffsets contains garbage even if dynamicOffsetCount
// is set to 1. dawn_native will happily read it.
