  [BOLT][DWARF] Fix out of order rangelists/loclists (#81645)

GCC can generate rangelists/loclists that are out of order. Fixed so
that we don't assert, and instead generate partially optimized list.
Through most code paths we do sort rnglists/loclists, but not for
loclist for a path where BOLT does not modify a function. Although it's
nice to have lists sorted, this implementation shouldn't rely on it.
This also fixes an issue if we partially capture a list we would write
out *end_of_list in helper function. So tools won't see the rest of the
addresses being written out.
