[Release] v0.8 Release Planning

Planning thread: https://github.com/apache/tvm/issues/8976.

Thanks to everyone who contributed in the past cycle! We would love to use the thread to plan for the v0.8 release. The community has always been focusing on high quality releases. This process can take several weeks according to past releases, to allow us to collectively work together on items and track things that needs to be merged.

In the next few days we will be populating the release note in this thread. Most release note content will be derived from our monthly report.

@vinx13 and I volunteered to manage the release, and @haichen and @yzhliu will mentor us as PMC members.

Please don’t hesitate to share your thoughts :slight_smile:
