[LiveDebugValues][NFC] 0/4 Move LiveDebugValues source file ahead of refactor

[jmorse]

Summary

This is the base patch of the stack from D83046, where a new implementation of the pass is being merged in. To allow arc and other tools to construct the stack correctly, this base patch moves one source file, ahead of other things being built around it.

(No functional change).
