aarzilli 5a947bceff proc: always resolve array types even if they don't appear in the
program

When evaluating type casts always resolve array types.

Instead of resolving them by looking up the string in debug_info
construct a fake array type so that a type cast to an array type always
works as long as the element type exists.

We already did this for byte arrays, this commit extends this to any
array type. The reason is that we return a fake array type (that
doesn't exist in the target program) for the array of a channel type.

Fixes #1736
