[MLIR] Add an install target for mlir-libraries

[lanza]

Summary

This is required for the distribution system for installing the
mlir-libraries component. This is copied from clang's equivalent
feature.

This should be MLIR_LIBS, right?

Putting back in your queue to address the comment.

Nope, MLIR uses the extra ALL for some reason: https://github.com/llvm/llvm-project/blob/main/mlir/cmake/modules/AddMLIR.cmake#L442

Right, but right above this you're doing a get_property into the MLIR_LIBS variable.
