new 7de71c5937 [fix](planner) Keep type of null literal expr when register
conjuncts (#16147)
7de71c5937 is described below
commit 7de71c5937dc8c14caacee4f223512c9c0af4e3f
Author: AKIRA <33112463+kikyou1...@users.noreply.github.com>

[fix](planner) Keep type of null literal expr when register conjuncts
(#16147)
For now, type information of child expr which is `NullLiteral` would get
lost in the `CastExpr#getResultValue`,
this will produce a `NullLiteral` with `Null ` type which cause BE core
when doing cast
