compiler: traverse expressions when exporting constants

When exporting a constant A that is expressed through a constant
B from another package, it is necessary to traverse an expression
representing the constant A to generate a sequence of type casts
from the constant B. Current implementation doesn't collect types
of constants contained in such expressions. This change fetches
these types.

Fixes golang/go#51291
