avcodec/hwconfig: Move HWACCEL_CAP_* to a new header

libavcodec/hwconfig.h currently contains HWACCEL_CAP_* flags
as well as the definition of AVCodecHWConfigInternal and some
macros to create them.

The users of these two are nearly disjoint: The flags are used
by files providing AVHWAccels whereas AVCodecHWConfigInternal
is used by files providing codecs (for FFCodec.hw_configs).

This patch therefore moves these flags to a new file hwaccel_internal.h.
