Various refactors to the LTO handling code
In particular reducing the sharing of code paths between fat and thin-LTO and making the fat LTO implementation more self-contained. This also moves some autodiff handling out of cg_ssa into cg_llvm given that Enzyme only works with LLVM anyway and an implementation for another backend may do things entirely differently. This will also make it a bit easier to split LTO handling out of the coordinator thread main loop into a separate loop, which should reduce the complexity of the coordinator thread.

rustc_std_internal_symbol is meant to call functions from crates where
there is no direct dependency on said crate. As they either have to be
added to symbols.o or rustc has to introduce an implicit dependency on
them to avoid linker errors. The latter is done for some things like the
panic runtime, but adding these symbols to symbols.o allows removing
those implicit dependencies.

Move metadata object generation for dylibs to the linker code
This deduplicates some code between codegen backends and may in the future allow adding extra metadata that is only known at link time.
