[Thread] add "owner: google" for Thread HAL

This is for bypassing frozen HAL check on release branches.
Background:
We need to write code in the tethering module that depends on the
HAL interface and that code will be auto-merged to udc-mainline-prod
branch.

Merged-In is added to stop this CL from auto-merged to the main branch

Test: build
Bug: 296211911
