[suggested files] Swap the new flag from Drive to local.

We are in the process of separating Drive files and local files into
separate flags, which were previously both controlled by the same flag
(enable-suggested-files).

https://chromium-review.googlesource.com/c/chromium/src/+/3162683 moved
drive files into a new flag (enable-suggested-drive-files). However,
there is a Finch experiment linked to the original flag which should be
kept linked to the Drive files.

So this CL makes the following changes:
- The [enable-suggested-drive-files] flag is removed.
- Drive files are gated under the original [enable-suggested-files]
- Local files are gated under a new [enable-suggested-local-files]
This effectively looks like a a swap between local and drive file flags.
