143503: sql: remove plan node visitor and observer r=mgartner a=mgartner

#### sql: add SetInput method to planNode interface

The `SetInput` method has been added to the planNode interface. It will
be used in future commits.

Release note: None

#### sql: use planNode methods to replace unwrapped planNodes

The `(*planNodeToRowSource).SetInput` method now uses the `InputCount`,
`Input`, and `SetInput` methods of `planNode`, instead of `walkPlan`, to
traverse and replace nodes in the plan node tree. This continues the
effort to deprecate and remove the plan node walkers (see #137620 for
more details on the motivation for this).

Release note: None

#### sql: use planNode methods to traverse CDC planNodes

CDC plan node trees that previously used plan visitors and observers now
use the `InputCount`, `Input`, and `SetInput` methods of the `planNode`
interface to traverse and manipulate the plan node tree. This continues
the effort to deprecate and remove the plan node walkers (see #137620
for more details on the motivation for this).

Release note: None

#### sql: remove unused planVisitor and planObserver

Release note: None

#### sql: rename walk.go to plan_names.go

This file has been renamed to reflect that it no longer contains any
logic for walking plan node trees. It only contains logic related to
plan node names.

143506: explain: fix plan gist decoding with nil catalog r=yuzefovich a=yuzefovich

Previously, when catalog wasn't specified during plan gist decoding, we forgot to decode the table ID. This would lead to unexpected remainder of the gist that could result in unexpected behavior, and this is now fixed. Only the "external" variant of decoding is affected, so I decided to not include the release note.
