  Log Message:
  -----------
  Add macro to suppress -Wunnecessary-virtual-specifier (#139614)

Followup to #138741.

This adds the requested macro to silence
`-Wunnecessary-virtual-specifier` when declaring virtual anchor
functions in `final` classes, per [LLVM
policy](https://llvm.org/docs/CodingStandards.html#provide-a-virtual-method-anchor-for-classes-in-headers).

It also cleans up any remaining instances of the warning, allowing us to
stop disabling it when we build LLVM.
