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.
