* [MLIR] Clean up MLIR related CMake files

This PR prepares the introduction of src/contrib/mlir/tools and LIT testing by
refactoring and cleaning up the common part with src/contrib/mlir/compiler:

- Common code for src/contrib/mlir/tools and src/contrib/mlir/compiler is
moved to src/contrib/mlir/CMakeList.txt.
- More generic code, common for src/contrib/mlir/* and LIT configuration
files, is moved to cmake/external_mlir.cmake with pre-existing similar code.
- Redundant environment var LLVM_DIR is removed in favor of LLVM_CMAKE_PATH.
- Redundant cmake messages are removed.

* Replacing LLVM_CMAKE_PATH with LLVM_DIR

* [MLIR] Add config files for LIT

LIT is the LLVM testing tool that is used in LLVM and MLIR. It's
necessary to enable all the MLIR testing in nGraph. This will provide
a complementary finer grain level of testing than the one currently done
with gtest. LIT will allow testing each MLIR-based nGraph transformation
without having to run the whole nGraph pipeline. For example, we will be
able to write an nGraph dialect input, invoke an single MLIR transformation
on it and check that the output is the expected.

This PR adds the basic configuration files to enable LIT tool
in nGraph for MLIR Compiler. `affine_lowering/lit_test.mlir` is a
dummy test to exercise the new testing feature. Lit testing will be
enabled in CMAKE in a subsequent PR.

This PR is a stepping stone towards unifying nGraph MLIRCompiler printing
flags with those used in MLIR. It enables flag -print-ir-after-all
implemented in MLIR pass manager and adds flag -print-ngraph-ir-after-all
to MLIRCompiler so that we can use it to dump IR for those transformations
that we do directly in MLIRCompiler without using a proper pass. Eventually,
everything should be working as a pass and the nGraph variant of the
flag shouldn't be needed. NGRAPH_MLIR_DUMP_ALL macro is no longer
needed.
