Support BC formats as the first extension in Dawn

Browse Source 
This patch refactors the current implementation of BC formats to treat
it as the first extension in Dawn and adds all the related tests.

Note that in Dawn all the extensions are disabled unless we enable them
when we create the device, which means the BC formats can only be used
when we enable the related extension on the creation of the device, and
the creation of the device will fail if the adapter does not support the
extension
