Add beautify format for ALTER ROLE and CREATE ROLE SETTINGS

[Copilot]

ALTER ROLE statements with SETTINGS clauses were not respecting beautify mode, rendering all settings inline instead of multi-line.

Changes

• AlterRole.FormatSQL() - Use formatter.Break() before SETTINGS keyword and indent each setting clause
• RoleSetting.FormatSQL() - Replace whitespace separators with formatter.Break() to separate setting components (value, MIN, MAX, modifiers) onto individual lines
• CreateRole.FormatSQL() - Apply same pattern for consistency

Example

Before:

ALTER ROLE r3_01293 SETTINGS max_memory_usage=5000000 MIN 4000000 MAX 6000000 WRITABLE;

After (beautified):

ALTER ROLE r3_01293
SETTINGS
  max_memory_usage=5000000
  MIN 4000000
  MAX 6000000
  WRITABLE;

Compact mode output remains unchanged.

Pull request overview

This PR fixes ClickHouse SQL beautify formatting for ALTER ROLE and CREATE ROLE statements that include SETTINGS, ensuring settings are rendered on multiple lines (with indentation) in beautify mode while keeping compact formatting unchanged.

Changes:

• Update AlterRole.FormatSQL() and CreateRole.FormatSQL() to Break() before SETTINGS, indent the settings list, and break between items.
• Update RoleSetting.FormatSQL() to use formatter.Break() between setting components (pairs/modifier) so multi-part settings become multi-line in beautify mode.
• Refresh beautify golden fixtures for alter_role.sql and create_role.sql to match the new output.
