remove llvm_enzyme and enzyme fallbacks from most places Using dlopen to get symbols has the nice benefit that rustc itself doesn't depend on libenzyme symbols anymore. We can therefore delete most fallback implementations in the backend (independently of whether we enable enzyme or not). When trying to use autodiff on nightly, we will now fail with a nice error if and only if we fail to load libEnzyme-21.so in our backend. Verified: Build as nightly, without Enzyme Build as nightly, with Enzyme Build as stable (without Enzyme) With this PR we will now run `tests/ui/autodiff` on nightly, the tests are passing. r? `@kobzol` |

The codegen crate contains the code to convert from MIR into LLVM IR,
and then from LLVM IR into machine code. In general it contains code
that runs towards the end of the compilation process.
For more information about how codegen works, see the rustc dev guide.
