When CONFIG_LOG_OUTPUT is set, it indicates that logging strings
are formatted by the application (using log_output module). It is
not needed when backend works in the dictionary mode. So far
LOG_OUTPUT was set also when dictionary mode was used and that
prevented removing of the logging strings from binary which is
an important feature of the dictionary logging.

The `LOG_BACKEND_FORMAT_TIMESTAMP` Kconfig currently depends on
a list of hardcoded backends.
Let's modify it to depend on an intermediary Kconfig
`LOG_BACKEND_SUPPORTS_FORMAT_TIMESTAMP` instead, which can be
selected by a OOT log backend.
Updated all exisitng supported backends to select this new
Kconfig.

This is mainly to reduce clutter in `subsys/logging`, but also to make
backend management slightly easier.
