LibDebug: Move Dwarf::LineProgram into Dwarf::CompilationUnit

Browse source 
Previously, the LineProgram objects were short-lived, and only created
inside DebugInfo::prepare_lines() to create a vector of sorted LineInfo
data.

However, Dwarf::LineProgram also contains other useful data, such as
index-to-string mapping of source directories and filenames.

This commit makes each Dwarf::CompilationUnit own its
Dwarf::LineProgram.
DebugInfo::prepare_lines() then iterates over the compilation units to
prepare its sorted vector of lines.
