  [flang][openacc] Do not loose attributes on folding (#80516)

hlfir.declare introduce some boxes that can be later optimized away. The
OpenACC lowering is currently setting some attributes on FIR operations
to track declare variables. When the boxes are optimized away these
attributes are lost. This patch propagate OpenACC attributes from
box_addr op to the defining op of the folding result.
