Name IDC p4wq threads. Unfortunately the idc threads only get their names after they are needed for the first time. Until that time they appear as unnamed (a hex number) threads on core 0. There is also one funny thing. There is static thread reserved for core 0, but that is never activated, and it remains there as a hex number forever. However, in this simple and risk free convenience fix, I do not dare to touch that. Maybe later. Signed-off-by: Jyri Sarha <jyri.sarha@linux.intel.com>

Pull request overview
This PR improves runtime observability in the Zephyr IDC implementation by assigning deterministic names to the per-core IDC P4WQ threads, avoiding “unnamed/hex” thread entries in thread listings until first use.
Changes:
- Add per-core thread name construction in
idc_init_thread(). - Set the P4WQ static thread name via
k_thread_name_set()after enabling the static thread.
💡 Add Copilot custom instructions for smarter, more guided reviews. Learn how to get started.
