All the fields of FFVkCodecMap are either decoder-only or encoder-only (with the latter being unused and unset for now). Yet there is already a per-decoder struct containing static information about these decoders, namely VkExtensionProperties. This commit merges the decoder-parts of FFVkCodecMap with the VkExtensionProperties into a common structure. Given that FFVkCodecMap is now unused, it is removed.
