[BOLT][DWARF] Change rangelists to use DW_RLE_offset_pair
Before we always used DW_RLE_startx_length. This is not very efficient and leads
to bigger .debug_addr section. Changed it to use
DW_RLE_base_addressx/DW_RLE_offset_pair.
clang-16 build in debug mode
llvm-bolt ran on it with --update-debug-sections
