feat(config): add `no-import-type-side-effects` rule of `@typescript-eslint`

Describe the feature

Currently, @typescript-eslint/consistent-type-imports is set as the typescript-eslint rule.

eslint/packages/eslint-config/src/flat/configs/typescript.ts

Lines 64 to 67 in 1352078

    
           '@typescript-eslint/consistent-type-imports': ['error', { 
        
             disallowTypeAnnotations: false, 
        
             prefer: 'type-imports', 
        
           }],

Since fixStyle is not specified, I think fixStyle: separate-type-imports will be applied.

I would like to suggest enabling @typescript-eslint/no-import-type-side-effects along with fixStyle: separate-type-imports being applied.
By adding this rule, it is possible to suppress variations in separate-type-imports and inline-type-imports on the user side.

However, I think whether to add a rule that disallows inline types to the official ESLint rules is an issue that requires discussion.
