Migrated `SelectField` tests to @testing-library/react

[piotrpospiech]

• Migrated MUI, AntD, and Semantic tests
• Tests weren't moved to the suites. They still need refactoring, but it is a good starting point. At least the enzyme was removed.
• I didn't check skipTestIf(options?.theme === 'antd') tests in suites. Maybe we should implement them in the packages/uniforms-antd/__tests__/SelectField.tsx file.
• I left this comment as some of tests can be moved to suites in the future.

  // FIXME: MUI select does not work with new RTL test implementation
  // suites.testSelectField(theme.SelectField, { showInlineError: true });
