Unset maxlength on EntityAutocomplete as it restrict to add more nodes on condition

Problem/Motivation

The form element "EntityAutocomplete" extends "Textfield form element.
In this way, this form element inherit "#maxlength" property (with a value to 128 characters).

to includes multiple nodes, I purpose to unset this property instead of set a default maxlength.

Steps to reproduce

Add visibility conditions on block -> set multiple nodes (total count of characters on fields more than 128) -> we are not able to save the condition due to maxlength set 128

Proposed resolution

I purpose to unset this property instad of set a default maxlength.
