target/arm: Implement FPCR.EBF=1 semantics for bfdotadd()
Implement the FPCR.EBF=1 semantics for bfdotadd() operations:
* is_ebf() sets up fpst and fpst_odd
* bfdotadd_ebf() implements the fused paired-multiply-and-add
operation that we need
The paired-multiply-and-add is similar to f16_dotadd() and
we use the same trick here as in that function, but the inputs
here are bfloat16 rather than float16.
