  -----------
  [clang] Cleanup docs and code for legacy no_sanitize attributes (NFC). (#161311)

Update generated docs for legacy attributes:

* no_sanitize_(address|thread|memory)
* no_address_safety_analysis

Those are older forms of no_sanitize("list", "of", "sanitizers")
attribute. They were previously as various spellings of the same
attribute, which made the auto-generated documentation confusing.

Fix this by explicitly making them three different attributes. This
would also allow to simplify the delegation to the new no_sanitize form
slightly, as we can instead rely on auto-generated code to check that
TSan and MSan can't be disabled for globals.
