fws: Make fws policy available to lacros

This CL exposes the floating workspace (fws) enabled policy to be
seen on the lacros side.

A followup CL will use this policy flag to tie some aspects of
Desk Profiles with fws to allow filtering of windows by profile.

Low-Coverage-Reason: TRIVIAL_CHANGE This is a renaming.

BUG=b:323015572
