LOG: [lldb] Remove Function::GetAddressRange usage from the gui (#130991)

m_disassembly_range was used only to prune the list of breakpoints to
those that are in the current function. This isn't really necessary, as
the list is only used to highlight instructions with breakpoints on
them, and an unpruned list works just as well for that.

The shouldn't make things slower, since we still needed through iterate
through all breakpoints to create the list, and I doubt anyone will
notice the memory used to store the extra breakpoints.
