This reverts commit 0036bbd0.

Reason for revert: Ran out of time to try the development pipeline

DETAILS: Just whitespace changes from the original.

Original change's description:
> [TTS] Write snippet to UKM for offline development
>
> Writes a snippet-hash and doc-id to UKM iff a command-line flag is
> set that allows this development-only data to be logged. Disabled
> on Beta and Stable channels.
>
> See go/ukm-cs-5, go/ukm-dev-data, go/cs-sanitized for details.
>
> Unfortunately our ContextualSearchDelegate cannot decode a JSON 64bit value
> so we now expect to receive these new data in string format.
>
> Also fix a bug in the existing Ranker code: the native logger cannot log
> 64-bit values, so we rename some misleading methods.  Also, we need to break
> these new data up into high/low 32-bit values when we log to Ranker.
>
