openvino: Add threading option supporting tbb and omp

[Greendogo]

Specify library name and version: openvino/*

Adds the option to set the threading cmake option to either tbb or omp.

Currently has an issue upon cmake config with projects using this option with openvino.

• I've read the contributing guidelines.
• I've used a recent Conan client version close to the currently deployed.
• I've tried at least one configuration locally with the conan-center hook activated.

Thanks!

You will need to add llvm-openmp dependency for OpenMP support, since it's (a) not available for Clang and AppleClang out of the box and (b) you will need to export compiler-specific linker flags for it otherwise.

I see that #pragma omp is being used in public headers (https://github.com/openvinotoolkit/openvino/blob/2024.0.0/src/core/include/openvino/core/parallel.hpp#L186-L190) as well, so you will need to set appropriate cflags and cxxflags for OpenMP regardless.

Somewhat blocked by #22353, though.

Suggested change

	self.requires("onetbb/2021.10.0")
	# https://github.com/openvinotoolkit/openvino/blob/2024.0.0/src/core/include/openvino/core/parallel.hpp#L186-L190
	self.requires("onetbb/2021.10.0", transitive_headers=True, transitive_libs=True)

TBB includes are being used in a public header, if I understand it correctly.

• seq is also available to disable the threading
• can we enable threading since 2024.4 ? because before that version OpenMP support was not enough tested / supported.
