HHH-16654 introduce a "default" fetch profile with eager to-ones in it
...
also, make the query translator always respect the fetch type specified
in the fetch profile (previously it would ignore it for statically-EAGER
many-to-ones, which was inconsistent and made little sense)

HHH-16650 fix for native queries with "unknown" numeric types on Oracle
...
Oracle reports FLOAT/DOUBLE PRECISION as NUMBER, which is wrong. The
workaround was to look at the scale, which it reports as -127 for
FLOAT. But certain other expression also get scale -127, and this
could cause truncation of least-significant digits when we read them
into a Java Double.
