Use TightLocalVector for AudioStreamWAV/MP3

[DeeJayLSP]

These data vectors are never resized except on instantiation, so we don't need them to be able to grow at a rate.

Not applicable to AudioStreamOggVorbis as it uses Vectors that are resized.

Made this partially in response to a regression from #104522 that has already been addressed. Resize on instantiation shouldn't be different between LocalVector and TightLocalVector. Still keeping it open for future codestyle purposes.

Looks good to me. I double checked all the uses of those vectors and confirm that they are all sized once and then re-used. So TightLocalVector makes sense and should save a bit of memory

Thanks!
