[ICRDMA] Fix msan RDMA allocator tests. EXT-1788

[dcherednik]

Changelog entry

The allocator is a static object so we can't place tests with different settings in the one process. The attempt to use non static version of allocator was wrong due to TLS cache issues inside slot allocator. So right now we just split tests in to 2 processes.
