lavc/ac3dsp: fix R-V CPU requirements
...
It probably will not matter on any real hardware, but the Zbb optimisations
do not require Zba. And then, we need HAVE_RVV to build the RVV stuff.

...
As we do not need to widen accumulators to 64 bits, we effectively get
double capacity for unrolling compared to the integer function. This
explains the slightly better performance gains.

riscv: test for assembler support
...
This should fix the build on LLVM 16 and earlier, at the cost of turning
all non-RVV optimisations off.
