avcodec/hevc_cabac: Let compiler count offsets

This is easily possible with an X macro.
Using an enum for the offsets also allows to remove
two arrays which are not really needed and will typically
be optimized away by the compiler: The first just exists
to count the number of syntax elements*, the second one
exists to get offset[CONSTANT]. These constants were
of type enum SyntaxElement and this enum was only used
in hevc_cabac.c (although it was declared in hevcdec.h);
it is now no longer needed at all and has therefore been
removed.

The first of these arrays led to a warning from Clang
which is fixed by this commit:
warning: variable 'num_bins_in_se' is not needed and will
not be emitted [-Wunneeded-internal-declaration]

*: One could also just added a trailing SYNTAX_ELEMENT_NB
to the SyntaxElement enum for this purpose.
