Implements wiring for Flight to have it's own "HostConfig" (#26590)

Part of #26571

Implements wiring for Flight to have it's own "HostConfig" from Fizz.

Historically the ServerFormatConfigs were supposed to be generic enough
to be used by Fizz and Flight. However with the addition of features
like Float the configs have evolved to be more specific to the renderer.
We may want to get back to a place where there is a pure FormatConfig
which can be shared but for now we are embracing the fact that these
runtimes need very different things and DCE cannot adequately remove the
unused stuff for Fizz when pulling this dep into Flight so we are going
to fork the configs and just maintain separate ones.

At first the Flight config will be almost empty but once Float support
in Flight lands it will have a more complex implementation

Additionally this commit normalizes the component files which make up
FlightServerConfig and FlightClientConfig. Now each file that
participates starts with ReactFlightServerConfig... and
ReactFlightClientConfig...
