LLVM Qualification Group - Backlog documentation and Discussion Updates (llvm#156184)

I have created backlog file for the Qualification group that contains
all the topics currently under discussion and I have added the new
section in the main group's page, referencing the backlog.

This Backlog will be used as the quick reference for anyone to know what
are the current topics under discussion and what priorities have been
given to them by the group.

Note for future editors: Add "Last updated:" comment on top of the
document, easily keep track of the last updated dates.
