Stabilize the `-Csplit-debuginfo` flag...
- ...on Linux for all values of the flag. Split DWARF has been
implemented for a few months, hasn't had any bug reports and has had
some promising benchmarking for incremental debug build performance.
- ..on other platforms for the default value. It doesn't make any sense
that `-Csplit-debuginfo=packed` is unstable on Windows MSVC when
that's the default behaviour, but keep the other values unstable.

Cache DWARF objects alongside object files in work products when those
exist so that DWARF object files are available for thorin in packed mode
in incremental scenarios.
