tests: kernel: pipe: Add concurrency test for zero-length pipes

This commit adds a new test case to the pipe API concurrency tests to
verify the behavior of zero-length pipes. The test ensures that writing
to a zero-length pipe blocks until data is read, and reading from a
zero-length pipe blocks until data is written—unless the pipe is closed,
reset, or the operation times out.

The test creates two pipes with zero-length buffers and spawns a helper
thread that performs complementary read/write operations. The two threads
use the pipe API as their only synchronization mechanism, validating the
correct blocking and wake-up behavior of zero-length pipes under
concurrent access.
