Fix AMD AV1 advanced encoder id in videoEncoderOptions table (#1771)

The AMD HW AV1 row used the simple encoder id (amd_av1) in the
advanced_name field instead of the advanced encoder id
(av1_texture_amf). Since no OBS plugin registers an encoder named
amd_av1, isEncoderRegistered always failed and the row was filtered
out of the Advanced-mode encoder dropdown on every AMD GPU.
