C2SoftVp8: List profile0 as supported profile

VP8 encoder/decoder plugins didn't correctly advertise the
profile they supported as profile enum wasn't defined earlier
for vp8.

Though Codec2InfoBuilder sets a default profile for vp8 codecs in
Android S, this change is still needed when this is installed on
older devices as part of mainline update.

Bug: 194154048

On Android R
Test: Install S swcodec mainline module on R and test
 run mts-user -m CtsMediaV2TestCases \
 -t android.mediav2.cts.EncodeDecodeAccuracyTest

On Android S
Test: revert the change in Codec2InfoBuilder that sets default
 vp8 profile and test the above MTS test
Test: atest CtsMediaV2TestCases
Test: atest VtsHalMediaC2V1_0TargetVideoDecTest
Test: atest VtsHalMediaC2V1_0TargetVideoEncTest
