* Move standalone_build target dir
* Move onnxImporterUnitTests target dir
* Combine onnx edytor tests
* Remove excessive target
* Merge onnx tests into one binary
part 1 : onnxImporterUnitTests into onnx_tests
* Merge onnx tests into one binary
part 2 : onnx_frontend_tests into onnx_tests
* Fix code style
* Update CI files

Rationale: Letter s and the end tells about implementation and

Frontend.
* Avoid loosing manifest filter flag
Issue occurred when gtest_filter was provided from command line
* Remove conflicting dependency
Linking to gtest_main (from googletest) via commonTestUtils caused
conflict while choosing main() function. OV defined in gtest_main_manifest
is prefered here as consider manifest file along with CLI arguments.
* Use proper naming
