[XRay][llvm+clang] Consolidate attribute list files

Summary:
This change consolidates the always/never lists that may be provided to
clang to externally control which functions should be XRay instrumented
by imbuing attributes. The files follow the same format as defined in
https://clang.llvm.org/docs/SanitizerSpecialCaseList.html for the
sanitizer blacklist.

We also deprecate the existing `-fxray-instrument-always=` and
`-fxray-instrument-never=` flags, in favour of `-fxray-attr-list=`.

This fixes http://llvm.org/PR34721.

[XRay][compiler-rt] Reduce XRay log spam

This change makes XRay print the log file output only when the verbosity
level is higher than 0. It reduces the log spam in the default case when
we want XRay running silently, except when there are actual
fatal/serious errors.

We also update the documentation to show how to get the information
after the change to the default behaviour.

We've recently changed the default for `xray_naive_log=` to be `false`
instead of `true` to make it more consistent with the FDR mode logging
implementation. This means we will now ask users to explicitly choose
which version of the XRay logging is being used.
