Andreas Rheinhardt 2df9c8da72 avcodec/e?ac3enc: Inform compiler about PutBitContext being blank ...

This turned out to be very beneficial: For GCC 13, the codesize
of ac3_output_frame_header went down from 4522B to 1247B and
from 10762B to 9298B for eac3_output_frame_header. For Clang 17,
the numbers went down from 3923B to 2477B and from 8338B to 6548B
(always with -O3).
