Define AOM_USAGE_* macros as unsigned constants
The AOM_USAGE_* macros are used with the "unsigned int g_usage" member
of the aom_codec_enc_cfg_t struct of the "unsigned int usage" parameter
of the aom_codec_enc_config_default() function. Defining these macros as
unsigned int constants allow them to be used in C++ templates with the
correct type inferred.
