Adapt to deprecation of ReactiveDataAccessStrategy

ReactiveDataAccessStrategy has been deprecated in Spring Data R2BC in
favor of R2dbcConverter (and StatementMapper and UpdateMapper). When
not using Boot, an R2dbcConverter bean is now defined by
AbstractR2dbcConfiguration. This commit updates
R2dbcDataAutoConfiguration to replace the definition of a
ReactiveDataAccessStrategy bean with the definition of an
R2dbcConverter bean.
