aco/gfx12+: do not use v_pack_b32_f16 to pack untyped data
GFX12 removed IEEE_MODE, and made its signalling NaN quieting the default.
Closes: #12251 (closed)
If someone feels bored, they can optimize do_pack_2x16 on gfx12 with v_perm_b32.

Equinix is shutting down its operations with us on April 30, 2025. They have graciously supported us for almost 5 years, but all good things come to an end. We are expecting to transition to new infrastructure between late March and mid-April. We do not yet have a firm timeline for this, but it will involve (probably multiple) periods of downtime as we move our services whilst also changing them to be faster and more responsive. Any updates will be posted in freedesktop/freedesktop#2011 as it becomes clear, and any downtime will be announced with further broadcast messages.
