Every render pass which invokes DrawIndexedIndirect, either directly or through a RenderBundle execution, is now preceded immediately by at least one validation pass. All indirect buffer offests used with DII are validated, and their validated values are copied into a separate scratch buffer (or zeroed out there, in the case of validation failure). All encoded DII commands are rewritten to use the validated parameters instead of the original ones.
