[igt-dev] [PATCH i-g-t v2 4/6] lib/intel_cmds_info: Add flags field to describe command properties

[Karolina Stolarek]

Blitter commands may have different properties depending on the
platform. Add a new field to blt_cmd_info struct to describe
their properties. Update block-copy definitions for DG2 and MTL
to use that field.
