g2: updates from cm

camera: Make sure we never claim to have multiple snaps if ZSL is disabled
This is mostly a userspace app bug, but still an incorrect behavior on
the HAL's part. In non-ZSL burst modes, the number of snaps should always
be 1

media_codecs: List only those we actually build
Listing codecs that aren't present breaks apps that scan all codecs
for a best match
