Update GitHub PR Greeter (#194307)

Following these two discussions:
* https://discourse.llvm.org/t/rfc-mention-our-ai-policy-in-the-greeting-message-for-first-time-contributors/,
* https://discourse.llvm.org/t/concerns-about-influx-of-ai-generated-bug-fixes/,

add a reference to the LLVM AI policy in the GH greeter. 

In addition:
* Update the message to include links to other relevant policies as
  well, since these are often shared during PR review.
* Add FAQ section and move some of the original content there.
* Include a request for people to confirm that they have familiarised themselves with
  the policies.
* Add `Hello @{self.author} :wave:` to make the greeting more personal.
