CMake support for iree::compiler::Dialect
In the Bazel configuration `iree-translate` depends on `"//iree/compiler/Dialect/VM/Target/Bytecode"`. This further pulls in several other dependencies. Right now, the build fails witt
```
[ 96%] Building VMEnums.h.inc...
mlir-tblgen: Unknown command line argument '-gen-iree-vm-op-encoder-defs'. Try: '../../../../../third_party/llvm-project/llvm/bin/mlir-tblgen --help'

```
This is because `iree-tblgen` has to be run and not `mlir-tblgen`. Within this context I noticed the comment "Runs iree-tablegen to produce some artifacts." in `iree_tablegen_library`. So is there a way to exec `iree-tblgen` instead of `mlir-tblgen` which I have overlooked or is the comment wrong? If the latter is true, do we need *another* `iree_tablegen_library` function which really runs `iree-tblgen` or do somebody sees a simple way how to fix this?
Closes #165
