Jack Christensen a581124dea Encode with driver.Valuer after trying TryWrapEncodePlanFuncs 
However, all builtin TryWrapEncodePlanFuncs check for driver.Valuer and
skip themselves if it is found.

Jack Christensen c4407fb36e Prevent infinite loop for driver.Valuer / Codec edge case 
A `driver.Valuer()` results in a `string` that the `Codec` for the
PostgreSQL type doesn't know how to handle. That string is scanned into
whatever the default type for that `Codec` is. That new value is
encoded. If the new value is the same type as the original type than an
infinite loop occured. Check that the types are different.

Jack Christensen 222e3b37bc Prefer driver.Value over wrap plans when encoding 
This is tricky due to driver.Valuer returning any. For example, we can
plan for fmt.Stringer because it always returns a string.

Because of this driver.Valuer was always handled as the last option. But
with pgx v5 now having the ability to find underlying types like a
string and supporting fmt.Stringer it meant that driver.Valuer was
often not getting called because something else was found first.

This change tries driver.Valuer immediately after the initial PlanScan
for the Codec. So a type that directly implements a pgx interface should
be used, but driver.Valuer will be prefered before all the attempts to
handle renamed types, pointer deferencing, etc.

Jack Christensen d4abe83edb Revert use generics for RangeCodec 
Reverted almost all of 976b1e0.

Still may consider a way to get DecodeValue to be strongly typed but
that feature isn't worth the complications of generics. Especially in
that applying this style to ArrayCodec would make Conn.LoadType
impossible for arrays.

fixed in this commit.

Jack Christensen 45a8b00271 Do not recursively call public PlanScan that caches 
Otherwise, wrapper types get cached. Wrapper types are expected to fail
most of the time. These failures should not be cached. In addition,
wrappers wrap multiple different types so it doesn't make sense to cache
results of a wrapper.
