ac3dec: fix processing of delta bit allocation information.

ac3: Remove ff_ac3_critical_band_size_tab.
...
It is only used to generate band_start_tab, which about the same size, at
runtime, so it's simpler just to always hardcode band_start_tab.

Move ff_ac3_critical_band_size_tab in ac3.c for non-hardcoded tables.
...
This symbol is only ever used to calculate the non-hardcoded tables, so
only enable it in that case, and static to the source unit that uses it.
