avcodec/dcaenc: Create encoder-adapted tables

Up until now, the encoder used the same tables that the decoder
uses to create its VLCs. These have the downside of requiring
the encoder to offset the tables at runtime as well as having
to read from separate tables for the length as well as the code
of the symbol to encode. The former are uint8_t, the latter uint16_t,
so using a joint table would require padding, but this doesn't
matter when these tables are generated at runtime, because they
live in the .bss segment.

Also move these init functions as well as the functions that
actually use them to dcaenc.c, because they are encoder-specific.
This also allows to remove an inclusion of PutBitContext from
dcahuff.h (and indirectly from all dca-decoder files).
