ANDROID: mm: Add vendor hook to thaw the killed process

Adding the vendor hook to thaw killed process without unfreezing freezer cgroup. Directly thawing the killed processes is very helpful for addressing the delayed thawing issue.

At the same time, if there are other processes in the freezer cgroup that have not been killed, this also helps avoid unnecessary thawing.
