Fix module annotation recognition

[MDoerner]

This PR changes two points regarding how the DeclarationSymbolsListener finds annotations:

1. It is now able to find member annotations even if these are line-continued. Previously, it was expecting at least one annotation per physical line, not logical line.
2. The determination of the declaration section is no longer delegated to the VBE. Now, it ends on the first line above the member annotations of the first module body element, i.e. on the first physical line above the block of consecutive logical lines right above the first module body element.
