feat(eslint-plugin): [consistent-type-exports] support TS4.5 inline export specifiers

[bradzacher]

PR Checklist

• Addresses an existing issue: TypeScript 4.5 Support #3950
• That issue was marked as accepting prs
• Steps in CONTRIBUTING.md were taken

Overview

• make sure the rule doesn't false-positive for inline type specifiers.
  • rule allows the following:
    • export { type T1, type T2 };
    • export { type T, value };
    • export type { T };
    • export { value };
• support the specifier in the fixers
  • export { type T1, T2 } is fixed to export type { T1, T2 };
• add an option to allow fixing "mixed" exports using inline specifier (default false)
  • when true, export { value, T }; is fixed to export { value, type T };
  • when false, it is fixed as before with a separate export type declaration.
