intel: Use Clear Color struct size.

The size of the clear color struct (expected by the hardware) is 8
dwords (isl_dev.ss.clear_value_state_size here). But we still need to
track the size of the clear color, used when memcopying it to/from the
state buffer. For that we keep isl_dev.ss.clear_value_size.

v4:
 - Add struct to gen11 too (Jason, Jordan)
 - Add field for Converted Clear Color to gen11 (Jason)
 - Add clear_color_state_offset to differentiate from
   clear_value_offset.
 - Fix all the places where clear_value_size was used.

v5 (Jason):
 - Split genxml changes to another commit.
 - Remove unnecessary gen checks.
 - Bring back missing offset increment to init_fast_clear_color().

v6 (Jason):
 - On init_fast_clear_color, change:
   addr.offset += 4 => sdi.Address.offset += i * 4
 - Use GEN_GEN instead of GEN_VERSIONx10.
