[docs] Remove experimental tag on Bloom filter predicate
Impala now supports pushing down Bloom filter predicate to Kudu,
by default [1].
Performance testing and associated changes were made to Kudu to reduce
regressions when Bloom filter predicate isn't effective [2].
So removing the experimental tag from the C++ client API docs.
