openmpi: migrate to Conan v2

[valgur]

In addition to typical migration changes also:

• Adds missing dependencies (requires rdma-core: add new recipe #18978 to be merged).
• Adjusts the CMake targets to match the targets exported by FindMPI.cmake.

test_package builds and runs, but displaying of help messages currently fails due to OpenMPI not being able to locate its res folder.

@valgur any way we can help this one moving along? (Also, could you please set the zlib requirement to the [>=1.2.11 <2] version range? Thanks!)

A review of the rdma-core recipe, which is a dependency of this one, would be of great help. I hope the build for that one succeeds now as well. Thanks!

Conan v2 pipeline ❌

Note: Conan v2 builds are now mandatory. Please read our discussion about it.

The v2 pipeline failed. Please, review the errors and note this is required for pull requests to be merged. In case this recipe is still not ported to Conan 2.x, please, ping @conan-io/barbarians on the PR and we will help you.
