Co-Authored-By: Adam Procter <adam.m.procter@intel.com>

Replace set with vector container in MLIR sub-graphs for
nodes, inputs and outputs. Using a set caused different order of
operations in MLIR code across different executions and this led to
differences in optimizations.

Dummy affine_lowering/lit_test.mlir test that served as initial testing
of LIT tool configuration is now removed.
