mainstream the "baked" lazyloader

[sqlalchemy-bot]

Migrated issue, originally created by Michael Bayer (@zzzeek)

looking to use "baked" for the two "IN" loaders, this should be mainstreamed in LazyLoader as well. no issues have been reported over the past year so it's time to see if this really holds up.

Use baked lazyloading by default

The lazy="select" loader strategy now makes used of the
:class:.BakedQuery query caching system in all cases. This
removes most overhead of generating a :class:.Query object and
running it into a :func:.select and then string SQL statement from
the process of lazy-loading related collections and objects. The
"baked" lazy loader has also been improved such that it can now
cache in most cases where query load options are used.
