  [clang] Remove `__is_layout_compatible` from revertible type traits list (#100572)

`__is_layout_compatible` was added in Clang 19 (#81506), and at that
time it wasn't entirely clear whether it should be a revertible type
trait or not. We decided to follow the example of other type traits.
Since then #95969 happened, and now we know that we don't want new
revertible type traits.

This patch removes `__is_layout_compatible` from revertible type traits
list, and leaves a comment what revertible type traits are, and that new
type traits should not be added there.

The intention is to also cherry-pick this to 19 branch.

(cherry picked from commit 3295d377f37a60597321f502d164b5d6b1948e28)
