Sam Brannen 833ab4d48f Introduce entry-based DSL for JdbcClient batch updates ...

Prior to this commit, JdbcClient's BatchSpec bound parameters to a
"current" batch entry and separated consecutive entries via add(). That
style was error-prone, since a missing add() still compiled but
silently merged parameters into a single entry. It also did not lend
itself to providing batch parameters dynamically — for example, from an
existing collection of domain objects.

To address that, this commit replaces the chaining style with
self-contained batch entries. BatchSpec now provides entry(...) methods
that define a single entry — via a Consumer<BatchEntry> callback, a
List of positional parameters, or a Map of named parameters — as well
as entries(...) methods that define one entry per parameter object.
Such calls can be freely combined within the same batch.

The new BatchEntry type exposes only the singular param(...) and
paramSource(...) methods. The add() method as well as the param(...),
params(...), and paramSource(...) methods have been removed from
BatchSpec.
