Remove the "VM" and "bytecode" features (#745)

* Remove the "VM" and "bytecode" features

The "bytecode" in `bc.{h,cpp}` was an initial attempt at a serialized encoding for the Slang IR, but we now have the `ir-serialize.{h,cpp}` approach which was has been kept up to date much better.

Similarly, the "VM" in `vm.{h,cpp}` was intended to be a system for interpreting Slang code in the bytecode format directly (so that you could load and evaluate code in a Slang module in a lightweight fashion). This never got used past a single test, which we eventually disabled.

There are good ideas in some of this code, but at this point the implementations have bit-rotted to a point where trying to maintain it is more costly than it would be to re-created it if/when we ever decide these features are important again.

* fixup: remove slang-eval-test from Makefile
