[libc++][CI] Moves CI badge to main README.

[mordante]

The current CI badge is currently in libc++ documentation. This does not seem the right place:

• The typical location on GitHub is on the main README.
• The documentation is shipped as part of the release:
  • This link does not work in off-line mode. Currently our documentation works in off-line mode.
  • The status in the release documentation does not reflect the status of the shipped library. So users looking at it may see a red status and get confused.

This moves the badge to the README.

This makes sense to me -- I only wonder if we want to put this in a less prominent location since this is the README for the whole LLVM project, and the libc++ CI status is only relevant for a small portion of the project.

But I totally agree that it doesn't belong in the documentation -- I think I had raised that concern in the original patch that added it and I appreciate that you took it on yourself to fix the issue!

I checked and libc++ is currently the only scheduled CI job. I hope other subprojects will add their badges when they do so. I added @tstellar as reviewer since he reviewed the other badge we have.

This is fine with me. If people don't like it we can always move it somewhere else.

[ldionne]

Ok, great, fine with me as well then.

Thanks for the reviews!
