radeonsi: add has_draw_indirect_multi flag

Prefer to use DRAW_(INDEX)_INDIRECT_MULTI when available in the firmware.

Versions for SI and CI already added as provided by the firmware team, but
keep in mind that they won't currently be used since the radeon kernel module
has no interface to query the firmware version.
