perf dwarf-aux: Handle array types in die_get_member_type

Browse source

When a struct member is an array type, die_get_member_type() would stop
iterating since array types weren't handled in the loop. This caused
accesses to array elements within structs to not resolve properly.

Add array type handling by resolving the array to its element type and
calculating the offset within an element using modulo arithmetic

This improves type annotation coverage for struct members that are
arrays.
