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 89f69aaea9 Date text encoding includes leading zero for month and day 
e.g. 2000-01-01 instead of 2000-1-1. PostgreSQL accepted it without
zeroes but our text decoder didn't. This caused a problem when we needed
to take a value and encode to text so something else could parse it as
if it had come from the PostgreSQL server in text format. e.g.
database/sql compatibility.

Jack Christensen 0d5d8e0137 Fallback to other format when encoding query arguments 
The preferred format may not be possible for certain arguments. For
example, the preferred format for numeric is binary. But if
shopspring/decimal is being used without jackc/pgx-shopspring-decimal
then it will use the database/sql/driver.Valuer interface. This will
return a string. That string should be sent in the text format.

A similar case occurs when encoding a []string into a non-text
PostgreSQL array such as uuid[].

Jack Christensen 989a4835de Remove rune to text conversion

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.
