covoar: Store address-to-line info outside of DWARF

This adds the AddressToLineMapper class and supporting classes to
assume responsibility of tracking address-to-line information.

This allows the DWARF library to properly cleanup all of its resources
and leads to significant memory savings.

Closes #4383
