I am not sure it is better to move these to the remoting_options. These are
enable flags. Options to me mean more like feature or implementation flags.

Only the values declared in declare_args() can be overridden in gn args. These 2
were not in declare_args(). Note that remoting_options.gni also has
declare_args() section with some values there. Every other value that's not in
declare_args() is a function of these args and the build environment (such as
is_os flags).
The difference between remoting_options.gni and remoting_enable.gni files is
completely unclear, and I'm not sure we need both. For example, why
enable_remoting_host was in this file, while remoting_multi_process is in
remoting_options.gni? For now I kept enable_remoting in this file because it is
referenced outside of the remoting directory, but in the future I think we
should merged these 2 files. I don't see any reason to keep them separate. WDYT?
