feat(printer): add per-node NEWLINE_ON_FLUENT_CALL attribute to BetterStandardPrinter

[MrPunyapal]

Summary

Add a per-node attribute AttributeKey::NEWLINE_ON_FLUENT_CALL so individual MethodCall nodes can opt into newline-on-fluent formatting without enabling the global newLineOnFluentCall() option.

Motivation

The printer currently only checks the global Option::NEW_LINE_ON_FLUENT_CALL flag. When a rule enables that option globally, every fluent chain across the processed codebase is reformatted. This causes undesirable, wide-ranging formatting changes. A per-node attribute lets rules request one-method-per-line formatting for specific nodes (for example, expect() chains) without affecting unrelated code.

This is the problem I'm facing for rector-pest chain rule which chains multiple statements in one chain and sometimes it creates very long line and there is no way around pretty print them instead of applying new line config to whole project.

Example

When creating a MethodCall node in a Rector rule, tag it to enable newline formatting:

use Rector\NodeTypeResolver\Node\AttributeKey;

$methodCall = new MethodCall($receiver, 'and', [$arg]);
$methodCall->setAttribute(AttributeKey::NEWLINE_ON_FLUENT_CALL, true);
