util: Drop the ENUM_PACKED macro
We have both PACKED
and ENUM_PACKED
macros which expand to the same
thing. PACKED
was based on a meson check for function attributes while
ENUM_PACKED
appears to be a legacy gallium thing which was based on
defined(__GCC__)
. This changes the one use of ENUM_PACKED
to PACKED
and
deletes ENUM_PACKED
.
