stb_vorbis: Increase max alloc buffer size for big Vorbis comments
stb_vorbis: Increase max alloc buffer size for big Vorbis comments

The previous max worked OK for audio data, but stb_vorbis recently gained support
for Vorbis comments, which can embed up to 2^32-1 bytes of data (e.g. cover art
encoded as base64).

We use 2^30 as max which should be sufficient for most files.

Fixes #41913.
