When CONFIG_KERNEL_COHERENCE is enabled, pend_locked() asserts
when wait_q is not in coherent memory. The k_pipes used in
the pipe_api tests are declared locally within the test. They
are located within the thread stacks and those wait_q inside
k_pipe struct are thus not considered in coherent memory.
To make them work, replace the local ones with a global
k_pipe object. Since each test initializes the pipe object
locally, the tests are not functionally changed.

Fix so the compiler does not throw a warning thinking that those
buffers may be used unitialized inside k_pipe_write/read().
Note clang does not the array size being of a variable size and
initialized as it throws a
"error: variable length array folded to constant array as an extension"
The issue was discovered with with gcc 14.2

This commit adds new test cases for the pipe API rework.
* basic.c: Sanity check for pipe operations.
* concurrency.c: Test pipe operations with multiple threads.
* stress.c: Test pipe operations under stress conditions.
And moves the old pipe test cases to the deprecated folder.
